This custom drone battery pack is engineered for UAV platforms that need a compact 3.7V LiPo cell with high-rate discharge, stable output, and repeatable cycle performance. As a drone battery manufacturer, Jianheng supports OEM and wholesale buyers with cell selection, pack assembly, and project-specific validation for professional drone battery programs. Model reference: OID0748145-5000mAh-3.7V-75C- 0102.
The cell platform is built around low internal resistance, high-rate pulse capability, and dependable discharge behavior under demanding UAV operating conditions. Detailed ratings, temperature performance, and test criteria are provided in the protected specification block so procurement teams can confirm each requirement before approval.
1. What is the recommended charging procedure for this battery?
Use a dedicated lithium-ion charger. The standard charge rate is 2.5A (0.5C) at 25C. A maximum charge current of 10A (2.0C) applies only when ambient temperature is between 20C and 45C. The charge cut-off voltage is 4.2V.
2. Can this battery be used in cold weather for outdoor drone flying?
Yes. The cell is built for low-temperature discharge and retains at least 65% of capacity at 0C and 50% at -10C when discharged at 0.5C.
3. What is the maximum continuous discharge current and how long can it sustain?
The peak discharge current is 375A (75C) for up to 20 seconds. For standard continuous discharge, use 2.5A (0.5C).
6. What is the expected cycle life of this drone battery?
Under standard charge and discharge conditions, the battery keeps more than 80% of rated capacity after 300 cycles.
