21700 Battery Pack for Drone: A New Solution for Longer Flight Time

When people talk about drone batteries, LiPo usually comes up first.

That makes sense. LiPo packs can deliver a lot of current, which is exactly what many multirotor drones need during takeoff, climbing and fast movement.

But not every UAV needs that kind of power all the time.

For mapping, inspection, surveying and other long-duration applications, the conversation is often different. The aircraft may spend a long period flying at a relatively steady power level, and carrying extra battery weight can become a problem.

This is where a 21700 drone battery becomes interesting.

The 21700 cell is larger than the familiar 18650 format and can offer higher capacity at the individual-cell level. With the right cell and pack design, it can be a practical option for a long endurance UAV battery.

It is not a magic upgrade for every drone, though. The aircraft’s power requirements still come first.

21700 Li-ion cells are becoming an interesting option for UAVs where energy density and endurance matter. For a broader introduction to drone battery chemistry, capacity, voltage and pack selection, see our LiPo Battery for Drone: Complete Guide for UAV Manufacturers and Buyers.

Why Are 21700 Cells Interesting for UAVs? The 21700 format was originally developed for applications where more energy could be packed into a similar physical space.

Compared with many traditional 18650 cells, a 21700 cell can offer higher capacity.

That can be useful when designing a battery pack for a long-endurance UAV.

Instead of simply adding more cells to increase capacity, the larger cell format may allow the battery designer to achieve a useful energy level with a different overall configuration.

There is another practical benefit.

Fewer cells can sometimes mean fewer electrical connections and a simpler pack structure, although this depends heavily on the required voltage and capacity.

For a production UAV, every little mechanical detail matters.

21700 lithium ion cells for UAV battery pack Long Flight Time Is Not Just About Capacity This is where battery discussions often become too simple.

A buyer might say:

“I need a 20,000mAh battery.”

But that number alone does not tell us how long the drone will fly.

Flight time depends on:

Battery voltage Capacity Battery weight Aircraft weight Motor efficiency Propeller selection Payload Flight speed Wind Operating temperature Actual current consumption Suppose you increase battery capacity by adding more cells, but the aircraft becomes substantially heavier.

Some of the additional energy is now being used to lift the battery itself.

So for long-endurance UAVs, I would pay close attention to Wh/kg, not just mAh.

21700 vs 18650 for Drone Battery Packs The 21700 format is larger than 18650, but that does not automatically mean it is better.

The comparison should look at the actual cell specifications.

Factor 21700 Cell 18650 Cell Physical size Larger Smaller Typical capacity Higher Lower Energy per cell Often higher Generally lower Pack flexibility Good Very good High-current options Available Widely available Long-endurance potential Strong Strong depending on cell Availability Broad Very broad For a new UAV platform, 21700 can be attractive when the design favors higher energy per cell.

For an existing aircraft with a very tight battery compartment, however, 18650 may still be easier to package.

The cell format should follow the aircraft rather than the other way around.

Where Does 21700 Drone Battery Make Sense? A 21700 Li-ion battery pack is particularly worth considering for UAVs where endurance matters more than extreme peak power.

Mapping UAVs Mapping drones often follow relatively predictable flight paths.

They may carry cameras or surveying equipment and spend a long time in the air.

A high-energy-density Li-ion pack can make sense here, assuming the aircraft’s current demand is within the cell’s capabilities.

Power Inspection Inspection drones may need to carry cameras, thermal sensors and communication equipment.

Again, battery weight matters.

If the drone can achieve the required power level with a lighter or more energy-dense pack, that can improve the useful flight time.

Surveying and Monitoring For surveying, environmental monitoring and similar applications, long endurance can be more valuable than short bursts of extreme acceleration.

This is one reason Li-ion UAV batteries deserve more attention in commercial drone development.

21700 Li-ion battery for long endurance mapping drone But What About Current? This is the part that should not be skipped.

Li-ion cells are not all the same.

A high-capacity 21700 cell may have excellent energy density but may not be suitable for a UAV that demands very high current.

Imagine a drone that needs a large current surge during takeoff.

The battery must be able to supply that current without excessive voltage drop or overheating.

So when selecting a 21700 drone battery, look beyond capacity.

Check:

Continuous discharge current Peak discharge capability Internal resistance Operating temperature Cell voltage Cell capacity Weight For some UAV platforms, a high-discharge LiPo pack will still be the better solution.

For others, 21700 Li-ion may provide a better balance.

Battery Weight Can Change the Result I have seen battery projects where the first idea was simply to add more capacity.

On paper, it looked good.

Then the battery became heavier, the drone consumed more power, and the expected flight-time improvement became much smaller than originally estimated.

This is why battery development should include actual aircraft testing.

A useful calculation is:

Battery energy = Voltage × Capacity

For example, a 22.2V, 20Ah battery stores approximately 444Wh of nominal energy.

But the drone cannot necessarily use all of that energy in practical operation.

There are voltage limits, reserve requirements, discharge losses and changing aircraft power demand.

The real-world flight result matters more than the theoretical number.

21700 Li-ion Can Be Useful for Long-Endurance UAV Design For a long-endurance UAV, the battery is part of a larger system.

You have:

Cell → Battery pack → Power system → Motors → Propellers → Aircraft → Payload

Changing one part affects the others.

A higher-energy battery may extend flight time, but if the battery becomes too heavy, the benefit starts to disappear.

A lower-current battery may be very efficient in cruise but struggle during takeoff.

This is why there is no universal “best 21700 battery” for every drone.

The best cell is the one that fits the actual load profile.

Designing 21700 UAV Battery Pack For OEM customers, the pack can be designed around the drone’s available space.

Typical specifications might include:

Cell configuration Nominal voltage Capacity Maximum current Battery dimensions Weight limit Connector type Cable length Charging method Battery monitoring requirements For example, a UAV manufacturer may have a long and narrow battery compartment.

A conventional rectangular battery may waste space.

A custom 21700 pack can potentially be arranged to make better use of that compartment.

This is one area where custom battery development becomes more useful than simply buying an off-the-shelf pack.

21700 Battery Packs for Commercial UAVs Commercial UAV customers usually care about more than flight time.

They may also ask:

How many cycles can the battery provide?

How consistent are the production batches?

Can the supplier maintain the same cell specification?

Can the pack be supplied in volume?

Can the connector and dimensions be customized?

These questions become important once the drone moves from prototype to production.

A battery that works well for one prototype is not necessarily ready for a fleet.

For a distributor, consistency between batches can be just as important as the initial battery capacity.

Is 21700 Better Than LiPo for a Drone? Not necessarily.

A high-discharge LiPo battery can still be a better option for:

FPV racing Heavy-lift UAVs Agriculture spraying drones High-current multirotors Applications with aggressive acceleration A 21700 Li-ion battery may be more attractive for:

Mapping Surveying Inspection Monitoring Long-endurance UAVs Relatively stable cruise applications The dividing line is really the aircraft’s power profile.

If you want to compare the two chemistries in more detail, see our guide to LiPo vs Li-ion drone batteries.

custom 21700 UAV battery pack manufacturing What Should Buyer Send to a 21700 Battery Manufacturer? If you are requesting a quotation, don’t only send:

“21700 battery, 20Ah, please quote.”

That leaves too many questions.

A much better inquiry includes:

Required voltage Target capacity Continuous current Peak current Maximum battery weight Available dimensions Connector type Charger requirements Estimated order quantity UAV application Even better, provide the drone’s motor, ESC and power-consumption data if available.

That allows the supplier to recommend a cell configuration rather than simply matching a number on paper.

Apsenx supplies customized UAV battery solutions, including Li-ion battery packs for applications where energy density and endurance are important. You can explore the UAV Battery product category for commercial UAV battery solutions and OEM/ODM projects.

A Practical Example Imagine a mapping UAV that consumes around 500W during normal cruise.

A battery with approximately 500Wh of nominal energy might appear to provide around one hour of theoretical operation.

But real operation is not that clean.

The aircraft may consume more power during takeoff and climbing. Wind can increase demand. The operator may also keep an energy reserve rather than completely draining the pack.

So perhaps the practical mission time is closer to 40–50 minutes, depending on the aircraft.

This is why I would rather test a 21700 battery pack on the actual UAV than promise a specific flight time based only on cell capacity.

FAQ What is a 21700 drone battery? A 21700 drone battery is a UAV battery pack built using 21700-format lithium-ion cells. These cells are larger than 18650 cells and can provide relatively high energy per cell.

Are 21700 batteries good for drones? They can be a good option for UAVs that prioritize energy density and endurance, particularly mapping, surveying and inspection platforms. The required discharge current still needs to be checked.

Can 21700 batteries provide longer drone flight time? Potentially. Higher cell-level capacity and good energy density can help reduce the amount of battery structure required for a given energy target, but actual flight time depends on the complete aircraft system.

Are 21700 Li-ion batteries better than LiPo? Not in every case. LiPo generally has an advantage in high-current applications, while 21700 Li-ion can be attractive for endurance-focused UAVs.

Can a 21700 UAV battery be customized? Yes. Cell configuration, capacity, voltage, dimensions, connectors, cables and other pack specifications can be customized for an OEM UAV project.

Agriculture Drone Battery: How to Choose the Right Battery Pack An agriculture drone has a very different working day from a normal camera drone.

It may take off with a full tank, fly low over a field, spray for several minutes, return to refill, and then do it again. Sometimes this cycle continues for hours.

That puts a lot of pressure on the battery.

For an agriculture drone manufacturer or distributor, choosing a battery is therefore not just about finding the biggest mAh number. The battery has to provide enough power, fit the aircraft, survive repeated working cycles and, importantly, avoid adding unnecessary weight.

A battery that looks impressive on a datasheet can behave very differently once the drone is carrying a full liquid tank.

Agriculture drones place unusually high demands on their batteries because of payload and repeated operation. For a broader look at LiPo battery selection for different UAV applications, see our LiPo Battery for Drone: Complete Guide for UAV Manufacturers and Buyers.

Start With the Drone, Not the Battery Before choosing an agriculture drone battery, I would first look at the aircraft itself.

A useful starting list is:

Maximum takeoff weight Empty drone weight Payload capacity Motor and ESC specifications Required voltage Average current Peak current Target flight time Battery compartment size This matters because agricultural drones vary considerably.

A small spraying UAV may use a relatively compact battery, while a larger commercial platform can require a much higher-capacity pack.

There is no single battery specification that fits every farming drone.

The Payload Changes Everything This is probably the biggest difference between agricultural drones and many other UAVs.

Imagine a spraying drone carrying 20 liters of liquid.

At the beginning of the flight, it is carrying:

Drone + battery + 20kg payload

Later, after spraying, much of that liquid is gone.

The aircraft becomes lighter.

The battery, however, weighs almost exactly the same from takeoff to landing.

So the battery needs to provide enough power for the most demanding part of the flight while still being light enough not to become unnecessary weight.

This is why battery selection and payload design should ideally be considered together.

Capacity Is Important, But Bigger Is Not Automatically Better A larger battery stores more energy.

That sounds like an easy way to increase flight time.

But a larger battery also adds weight.

Suppose a manufacturer increases the battery capacity by 30%, but the battery weight increases significantly at the same time.

The drone now has more energy available, but the motors also have more weight to lift.

The final flight-time improvement may be smaller than expected.

For agricultural UAVs, I would look at usable energy per kilogram rather than capacity alone.

This is where energy density becomes useful.

High Discharge Capability Matters During Takeoff Agriculture drones can be power-hungry, particularly when carrying a heavy payload.

The battery needs to handle high current during:

Takeoff Climbing Acceleration Wind resistance Heavy payload operation A battery with insufficient discharge capability can experience significant voltage drop under load.

The pilot may notice slower response or reduced power when the drone is carrying a full tank.

For this reason, a high-discharge farming drone battery is often more important than simply choosing a high-capacity pack.

The exact requirement depends on the motor and ESC system, though. There is little value in paying for extreme discharge capability if the aircraft never actually uses it.

LiPo Is Common for Agriculture Drones High-discharge LiPo batteries are widely used in heavy-lift and agriculture UAV applications.

The main attraction is straightforward:

high power output without an extremely complicated battery system.

A well-designed LiPo pack can provide substantial current for takeoff and heavy-load flight.

For a spraying drone, this can be useful because the aircraft may need strong thrust when the liquid tank is full.

However, battery weight still needs to be controlled.

A heavier battery means the drone has to work harder throughout the flight.

Battery Voltage Must Match the Power System Voltage is another specification that should be confirmed before requesting quotations.

The battery voltage must match the drone’s:

Motors ESCs Power distribution system Charger Battery management or monitoring system A higher-voltage pack is not automatically better.

Changing from one voltage configuration to another can affect motor speed, current and overall power-system behavior.

For an OEM customer, it is usually better to provide the battery supplier with the existing motor and ESC specifications rather than simply saying:

“I need a high-voltage agriculture battery.”

That gives the manufacturer something concrete to work with.

What About Brazil? Brazil is an interesting market for agricultural UAVs because large-scale farming operations can involve extensive fields and long working distances.

For operators, battery turnaround becomes important.

A drone that can only complete a short flight before waiting for a recharge may not be very productive, even if the battery itself performs well.

In practice, many commercial operators may need several battery packs per aircraft so that one pack is flying while another is being charged or prepared.

For distributors, this creates a different purchasing question:

Download the Medium app How many batteries does the customer actually need for one working drone?

Selling a single battery is one thing.

Building a practical battery package for a fleet is another.

Press enter or click to view image in full size

Middle East Conditions Can Be Hard on Batteries Heat is another factor worth considering for agricultural UAV operations in the Middle East.

High ambient temperatures can increase battery temperature during operation and charging.

The actual effect depends on the battery design, current load, aircraft cooling and operating environment.

For buyers in hot regions, I would not focus only on rated capacity.

It is worth asking suppliers about:

Operating temperature Charging temperature Discharge temperature Thermal management Storage requirements Testing conditions A battery that performs well in a cool factory environment still needs to be tested under realistic field conditions.

Southeast Asia: Humidity and Frequent Operation Southeast Asian agriculture can present a different combination of challenges.

High humidity, heat, frequent rain and intensive farming schedules can all affect how equipment is handled.

The battery itself should be stored and charged properly, but the entire UAV system also needs to be designed for the working environment.

For commercial buyers, battery connectors and pack construction deserve attention too.

It is not just the cells.

The wiring, connector, enclosure and mechanical protection all become part of the finished battery pack.

One Battery Specification Does Not Fit Every Farm A distributor selling agriculture drones across different countries may run into this problem quite quickly.

A battery suitable for a lightweight spraying drone may not work for a larger aircraft.

Likewise, a battery designed for a hot operating environment may need different testing and thermal considerations from one used in a cooler climate.

The customer’s actual UAV model should always be part of the quotation process.

For example:

RequirementWhy It MattersCapacityDetermines stored energyVoltageMust match power systemDischarge currentSupports high-power operationWeightDirectly affects payload and enduranceDimensionsMust fit battery compartmentCycle lifeImportant for fleet operating costTemperatureImportant in hot farming regionsConnectorMust match aircraft system

Battery Cycle Life Matters for Commercial Farming An agriculture drone may fly much more frequently than a recreational drone.

That means the battery can accumulate cycles quickly.

For a commercial operator, battery replacement becomes part of the operating cost.

A battery that provides good performance but loses capacity quickly may not be attractive over a full season.

This is why fleet operators should track battery condition rather than treating every pack as identical.

Capacity testing, internal resistance checks and flight-time records can help identify batteries that are beginning to perform differently.

When Should You Consider a Custom Farming Drone Battery? Custom battery development makes sense when the standard packs do not quite fit the aircraft.

Typical requirements might include:

Custom voltage Larger capacity Specific dimensions Maximum weight limit High discharge capability Special connector Longer cable Custom housing Fleet-specific battery configuration For example, an agriculture drone manufacturer may have a narrow battery compartment but require a relatively high-capacity pack.

Instead of forcing a standard battery into the available space, the pack can be designed around the aircraft.

For larger OEM projects, this can be a much more practical approach.

Apsenx provides customized UAV battery solutions for commercial drone applications. You can view the UAV Battery product category for available battery configurations and OEM/ODM options.

Buying Agriculture Drone Batteries in Bulk For distributors in Brazil, the Middle East or Southeast Asia, sample testing should happen before a large purchase.

I would suggest testing the battery on the actual agriculture drone and checking:

Takeoff current Full-load flight performance Battery temperature Voltage under load Actual flight time Charging time Capacity after repeated cycles This gives a much better picture than a product sheet alone.

For wholesale orders, consistency between batches becomes important as well.

If the first shipment performs differently from the second, the distributor has a problem even if both batteries technically meet the same printed specifications.

Which Agriculture Drone Battery Should You Choose? For most commercial agriculture UAV projects, the battery should be selected around the aircraft’s payload, power demand and operating environment.

A high-discharge LiPo can be a strong option for heavy spraying drones where takeoff and climbing require substantial power.

A higher-energy-density pack may be more attractive for lighter agricultural UAVs where endurance is the bigger concern.

And for OEM manufacturers, a custom battery can make sense when weight, dimensions or voltage requirements are difficult to meet with standard products.

The right battery is usually the one that works well with the whole aircraft — not simply the one with the largest capacity printed on the label.

FAQ What is the best battery for an agriculture drone? It depends on the drone’s weight, payload, voltage and current requirements. High-discharge LiPo batteries are commonly considered for heavy agricultural UAVs.

How long does an agriculture drone battery last? Flight time varies considerably depending on payload, battery capacity, aircraft weight, wind and spraying conditions. A full payload generally requires more power than an empty or partially loaded tank.

Are LiPo batteries suitable for farming drones? Yes. High-discharge LiPo batteries are widely used for agriculture UAVs because they can provide substantial power for heavy-load operation.

Can agriculture drone batteries be customized? Yes. Capacity, voltage, dimensions, connectors, wiring and other pack specifications can be customized for OEM agriculture drone projects.

Custom Drone Battery Pack Manufacturer: OEM Solutions for UAV Companies Drone battery is easy to buy when the aircraft is already on the market.

You find a battery with the right voltage, capacity and connector, place an order, and move on.

It becomes a different story when you are developing the drone yourself.

The battery may need to fit into a narrow compartment. The aircraft may require a particular voltage. The motors may pull a surprisingly high current during takeoff. Maybe the connector needs to sit on one side of the pack, or the battery needs to communicate with the drone’s power system.

At that point, a standard battery can become more of a limitation than a solution.

This is where working with a custom drone battery manufacturer can make sense.

For UAV companies, OEM battery development is not simply putting cells together. The battery needs to be designed around the aircraft.

Before developing a custom battery, it helps to understand how LiPo chemistry, voltage, capacity and discharge performance affect UAV battery selection. Our LiPo Battery for Drone: Complete Guide for UAV Manufacturers and Buyers provides a broader starting point.

What Does Custom Drone Battery Actually Include? When a customer says, “We need a custom battery,” there are usually several different things behind that request.

The customization may involve:

Cell type Cell configuration Voltage Capacity Discharge capability BMS Connector Cable length Housing Battery dimensions Weight Charging requirements Sometimes only the connector needs to change.

Sometimes almost the entire battery needs to be developed from scratch.

That is why a useful OEM discussion should start with the UAV rather than with a battery catalog.

Cell Selection Comes First The cell is the foundation of the battery pack.

A UAV manufacturer may be choosing between high-energy and high-power cells, depending on the aircraft.

For example, a long-endurance mapping drone may place more emphasis on energy density.

A heavy-lift agriculture drone may need much stronger discharge performance.

An FPV platform has yet another requirement.

A custom drone battery manufacturer should therefore look at the aircraft’s actual power profile before recommending a cell.

Important parameters include:

Nominal voltage Capacity Continuous current Peak current Cell weight Internal resistance Operating temperature Expected cycle life A 5,000mAh cell is not automatically better than a 4,000mAh cell if the aircraft needs substantially more current.

The “best” cell depends on the job.

For endurance-focused UAV projects, 21700 Li-ion cells can be another option worth evaluating. See our guide to 21700 battery packs for drones for more details.

BMS Design Is More Than a Protection Board For Li-ion UAV battery packs, the BMS can play an important role in monitoring and protecting the battery.

Depending on the project, the BMS may monitor:

Cell voltage Pack voltage Current Temperature Overcharge Over-discharge Short circuit Battery condition For some OEM projects, battery communication is also important.

The UAV may need information from the battery rather than simply receiving power.

That could include battery voltage, current, temperature, remaining capacity or other status information.

The exact BMS requirements depend on the aircraft’s electronics and communication architecture.

So it is better to define the BMS together with the drone manufacturer rather than adding a generic BMS at the end.

Press enter or click to view image in full size

The Connector Is Small Detail Until It Isn’t Battery connectors are easy to overlook during the early design stage.

Then the prototype arrives.

The connector is facing the wrong direction.

The cable is too short.

The plug interferes with the battery compartment.

Now a seemingly small problem requires a mechanical change.

For OEM UAV batteries, connector selection should consider:

Maximum current Connector dimensions Installation direction Locking mechanism Cable length Polarity Number of mating cycles If the battery will be replaced frequently in the field, the connector also needs to be practical for operators.

A drone used five times a day can put very different demands on a connector compared with a prototype flown once a week.

Housing and Battery Dimensions Matter Battery capacity is only one side of the design.

The physical shape can be just as important.

Imagine an aircraft with a battery compartment that is only 65mm high.

A standard battery may have enough capacity but physically cannot fit.

Another pack may fit but leave unused space.

For an OEM project, the battery housing can be designed around the available mechanical space.

Typical information includes:

Length × Width × Height

Maximum weight should also be provided.

If possible, the battery supplier should receive a drawing or 3D model of the battery compartment.

Even a simple dimension sketch is useful during the early stage.

Press enter or click to view image in full size

Prototype First, Production Later One thing I would strongly recommend for UAV companies is not to jump directly from a quotation to a large production order.

Build samples first.

A typical development process might look like:

Requirements → Cell selection → Battery design → Prototype → Testing → Revision → Final sample → Mass production

The first prototype may not be perfect.

Perhaps the battery is 150g heavier than expected.

Maybe the cable needs to move.

Perhaps the pack gets warmer than expected during climbing.

That is normal during development.

The useful part is finding these problems while there are still ten prototype batteries on the workbench rather than 2,000 finished packs in production.

Testing the Battery on the Real UAV Laboratory testing is important, but the real aircraft tells a different story.

A battery can pass a capacity test and still behave differently when connected to the actual UAV.

Subscribe to the Medium newsletter For prototype testing, consider checking:

Takeoff current Cruise current Peak current Voltage sag Battery temperature Flight time Charging behavior Physical fit Connector temperature Battery communication The test results can then be used to adjust the pack.

For example, if the battery has plenty of capacity but excessive voltage sag during takeoff, the problem may be the cell’s discharge capability rather than its capacity.

That distinction matters.

Prototype testing should also include proper charging, storage and inspection procedures. See our drone battery safety guide for practical battery handling advice.

Apsenx OEM Drone Battery Development For UAV companies looking for an OEM drone battery, Apsenx can support several parts of the battery development process.

Cell Selection We can help evaluate suitable lithium battery cells based on voltage, capacity, current requirements, weight and application.

BMS The BMS can be selected or developed according to the battery’s protection and monitoring requirements.

Connector The battery connector, cable length and wiring arrangement can be matched to the UAV design.

Housing Battery dimensions and mechanical structure can be developed around the available battery compartment.

Prototype Prototype packs can be produced for initial testing before moving toward larger production quantities.

This approach is useful for UAV companies that are still refining their aircraft.

What Information Should You Send to an OEM Battery Manufacturer? A detailed inquiry usually gets a much more useful response.

Instead of:

“Please quote 10,000mAh drone battery.”

Try to provide:

Application: Mapping / Agriculture / Inspection / FPV / Other Voltage: Required nominal voltage Capacity: Target Ah or Wh Continuous current: Normal operating current Peak current: Maximum current Dimensions: Maximum battery size Weight: Maximum acceptable weight Connector: Required connector Quantity: Prototype and production quantity

If available, also provide motor, ESC and flight-time information.

The more accurate the input, the less guessing is involved during battery development.

OEM Does Not Always Mean Completely New Battery This is another point worth making.

OEM development does not always mean designing a completely unique cell and enclosure.

Sometimes a customer only needs:

A different connector Different cable length Modified dimensions Different capacity New labeling A different housing Small changes to the existing pack Other projects require a completely new battery architecture.

Both can fall under OEM battery development.

The right level of customization depends on the drone and production volume.

Press enter or click to view image in full size

From Prototype to Volume Production Once the prototype has been approved, production consistency becomes the next concern.

For a UAV manufacturer, it is not enough for sample #1 to perform well.

The 100th and 1,000th battery should still meet the agreed specifications.

This is where cell matching, assembly quality, welding, testing and production controls matter.

For fleet operators and drone manufacturers, consistent battery performance makes logistics easier too.

If every battery behaves differently, flight planning and battery replacement become harder.

Custom Battery for Different UAV Applications Apsenx can work with different UAV battery requirements.

Agriculture UAVs Usually need strong discharge performance because of heavy payloads and demanding takeoff conditions.

Mapping UAVs Often place more emphasis on energy density and endurance.

Power Inspection May need a balance between battery weight, endurance and sensor payload.

Long-Endurance UAVs Can benefit from high-energy-density Li-ion battery configurations when the aircraft’s current requirements allow it.

FPV Usually requires a high-discharge battery capable of handling rapid current changes.

The battery design should follow the aircraft rather than trying to force every application into the same pack.

If your company is developing a commercial UAV for agriculture, inspection or mapping, our guide to industrial UAV battery solutions covers the battery requirements of these different applications.

Why OEM Battery Development Can Be Worth It A custom battery may cost more than a generic pack during the prototype stage.

That is not surprising.

But if the battery fits the aircraft better, uses the available space more efficiently and delivers the required current without unnecessary weight, the difference can become worthwhile once production begins.

For UAV companies, the battery is part of the aircraft design.

It affects payload.

It affects flight time.

It affects mechanical structure.

And it affects how the drone behaves under load.

That is why battery development is usually better handled as an engineering discussion rather than a simple product purchase.

Request UAV Battery Quote If you are developing a commercial UAV and need a custom battery pack, send the basic aircraft requirements first.

We can start with:

Voltage Capacity Current Battery dimensions Maximum weight Connector Application Estimated quantity For prototype projects, even an initial drawing and basic power data can be enough to start the conversation.
