OID 21700 5000mAh Low Temperature High Rate Drone Battery Cell for Reliable UAV Power
OID 21700 5000mAh 3.7V 25A 5C Low Temperature High Rate Drone Battery Cell
Every drone mission depends on one critical factor: power. Pilots often face voltage sag, short flight time, and sudden power loss in cold weather. The OID 21700 5000mAh 3.7V 5C cell solves these problems with low internal resistance and stable low-temperature performance, giving your drone reliable high-rate energy when you need it most.
User Pain Points and Solution
- Pain point: Common 21700 cells sag heavily under 25A load, triggering low-voltage cutoff and flight termination.
- Solution: OID 21700-5000mAh-3.7V-5C supports continuous 5C discharge with a 25A rating, maintaining a flatter voltage curve under load.
- Pain point: Cold weather reduces available capacity and increases internal resistance.
- Solution: Optimized low-temperature electrolyte and electrode design keep the cell responsive in freezing environments.
- Pain point: Inconsistent internal resistance causes heat buildup and unbalanced pack performance.
- Solution: Low impedance design reduces heat generation and supports tighter pack matching for longer cycle life.

How This Battery Creates Value
For drone manufacturers, using OID 21700 cells means higher energy density, less weight, and simpler pack assembly. A 3S2P pack built with this cell delivers 10Ah capacity and 50A continuous output, supporting heavier payloads and longer flight times. The low internal resistance also reduces voltage drop during fast throttle changes, giving the flight controller stable input voltage.
Safety and Certification
Safety is built into every layer: ceramic-coated separator, pressure relief vent, and rigid cylindrical steel case. The cell passes UN38.3 transport tests and MSDS compliance, and Jianheng supports full traceability from production to delivery.
Applications
- High-payload civilian drones
- FPV racing and freestyle drones
- Agricultural spraying drones
- Industrial inspection robots
- Portable power stations
- High-drain power tools
