Designed for Drone, FPV and RC Applications
A drone battery has to do more than store energy.
It must provide enough current during takeoff, acceleration, maneuvering, and payload operation while keeping battery weight and dimensions under control.
Our 7.4V LiPo battery series provides different capacity, size, and discharge combinations for different RC and UAV designs.
Typical applications include:
FPV drones and compact flying platforms
RC drones and aircraft
Small UAV systems
Aerial photography and inspection equipment
RC electronic systems
Robotics and mobile equipment
Custom battery-powered devices requiring a 7.4V platform
Battery selection should always be based on the actual motor current, ESC requirements, available battery compartment, payload, and target operating time.

How to Choose the Right 2S LiPo Battery
There is no single 7.4V drone battery that fits every aircraft.
For an OEM or replacement battery project, start with five parameters.
If the drone or RC device is designed for a standard 2S LiPo system, the battery has a 7.4V nominal voltage and reaches 8.4V when fully charged.
Do not select a battery based on voltage alone. Confirm the device and ESC voltage range before testing a replacement pack.
Higher capacity stores more energy, but it normally adds battery weight and volume.
A compact FPV or RC platform may prioritize a smaller and lighter battery. A larger UAV may prioritize runtime and choose a higher-capacity pack.
Our available cell capacities cover 1300mAh, 1400mAh, 1500mAh, 1800mAh, 2000mAh, 2400mAh, 2500mAh, 3000mAh, 3350mAh, 3550mAh, 3700mAh, 4000mAh, 5000mAh, and 6000mAh. More can be custom.
The C-rating determines how much current the battery can provide relative to its capacity.
Our current cell portfolio includes 15C, 20C, 30C, 40C, and 60C options.
High-discharge cells are useful when the system has higher motor current, fast acceleration, or large peak-current demand.
A higher C-rating is not automatically better for every project. The correct battery should match the actual continuous and peak current requirements of the aircraft.
Space inside an RC drone or UAV is often limited.
That is why we offer different pouch-cell dimensions at the same or similar capacity.
For example, a 2000mAh cell can be supplied in several formats. This gives engineers more flexibility when the battery compartment is narrow, thin, or long.
The battery connector must match the aircraft power system.
For custom projects, connector type, wire gauge, cable length, polarity, and balance leads can be configured according to your electrical design.
Battery Options for Different Design Priorities
Compact FPV and RC Platforms
For small battery compartments, lower-capacity cells such as 1300mAh to 2000mAh can reduce pack volume.
Several narrow and thin cell formats are available for space-constrained designs.
High-Current Drone Systems
For applications with higher current demand, 40C and 60C LiPo cells provide more discharge capability.
Selection should be based on the motor, ESC, propeller configuration, maximum load, and measured peak current.
Longer-Runtime UAV Applications
For projects where runtime is more important than minimum battery size, 4000mAh, 5000mAh, and 6000mAh options provide higher energy capacity.
The final battery should still be evaluated against aircraft takeoff weight and payload requirements.
Custom 7.4V LiPo Battery Packs
Many OEM drone projects cannot use an off-the-shelf RC battery.
The voltage may be standard, but the battery compartment, connector, current requirement, or mechanical structure can be different.
BLUMOTI can develop a custom 2S lithium polymer battery around your device requirements.
Custom options can include:
Battery capacity
Cell dimensions
2S pack structure
Discharge rate
Connector type
Power wire
Balance connector
Cable length
Label and branding
Battery insulation
Packaging
For a new UAV or RC battery project, providing the available battery compartment dimensions early in the design process makes cell selection faster.
2S LiPo Battery Solutions for OEM Buyers
For drone manufacturers, RC brands, equipment developers, and battery distributors, battery sourcing is not only a price comparison.
Compatibility must be verified before volume production.
A typical project can include:
Requirement review → cell selection → 2S pack design → sample evaluation → electrical testing → application validation → production
For faster evaluation, send us:
Required voltage
Target capacity
Continuous current
Peak current
Maximum battery dimensions
Target battery weight
Connector type
Wire length
Application
Estimated order quantity
Our team can then recommend an existing cell or evaluate a custom RC drone battery design.
Frequently Asked Questions
1,What does 2S mean on a LiPo battery?
2,Is a 2S LiPo battery 7.4V or 8.4V?
Both numbers are used for different states of charge.
A standard 2S LiPo battery is rated at 7.4V nominal voltage. Its voltage reaches approximately 8.4V when fully charged, or 4.2V per cell.
3,Can I replace a 7.4V RC battery with any 2S LiPo battery?
Not automatically.
You should check the capacity, connector, polarity, battery dimensions, discharge capability, maximum device voltage, and charging system before replacing an RC battery.
4,What C-rating should I choose for a drone battery?
Choose the C-rating according to the maximum continuous and peak current required by the drone.
A high-performance FPV or UAV platform may require a higher-discharge battery than a low-current RC device.
5,Is 40C better than 20C?
A 40C battery can support a higher current relative to the same capacity, but the best choice depends on the actual load.
Using an unnecessarily high C-rating does not automatically improve flight time.
6,How do I choose the right battery capacity for a drone?
Start with the required runtime, maximum battery weight, available battery compartment, and average current consumption.
Higher mAh usually means more stored energy, but also more weight and volume.
7,Can you customize a 7.4V LiPo battery for an OEM drone?
8,Do you supply FPV batteries and RC lithium polymer batteries in bulk?
