Tenpower INR21700-60XG 6000mAh 60A

Tenpower INR21700-60XG is a high-performance 21700 Li-ion cell with a capacity of 6000mAh and a discharge current of up to 60A. Thanks to the combination of high capacity and high current capability, it is suitable for building power packs for FPV drones, especially long-range and cruise builds where flight time is crucial.

The cell belongs to Tenpower's Ultra Power series and features a tabless design („tabless“). This reduces internal resistance, so the cell generates less heat under load and maintains voltage. According to the manufacturer, the internal resistance is max. 5mΩ. The continuous discharge current is 40A, or 60A with a temperature limit of 75°C.

The nominal voltage is 3,6V, and the maximum charging voltage is 4,2V. The cell should not be discharged below 2,5V. It features a flat positive terminal („flat top“) and no protection circuitry („unprotected“). It is therefore intended for packs or devices with their own overcharge and deep-discharge protection (BMS). The standard charging current is 3A (0,5C), maximum 16A.
