INR 21700 P42A 11.1V 4200mAh 3S1P Li-ion Drone Battery Pack,

Pro-Range INR 21700 P42A 11.1V 4200mAh 3S1P High-Discharge Li-ion Drone Battery Pack (SKU: 1424901)

The Pro-Range 3S1P Drone Battery Pack is engineered for demanding applications that require a lightweight, high-capacity, and high-discharge power source. It is constructed using three INR 21700 P42A cells connected in series (3S), a renowned cell known for its low internal resistance and excellent performance under continuous high load.

With a Nominal Voltage of 11.1V and a generous 4200mAh Nominal Capacity, this pack delivers substantial flight time. The battery is capable of a high continuous discharge rate of 40 Amps (approximately 9.5C) and a burst rate of 50 Amps (approximately 11.9C), ensuring your drone's motors receive the necessary current for aggressive maneuvers and stable flight. The unique triangular form factor is specifically designed for optimal fit and weight distribution within many standard drone frames. The pack includes necessary connectors for safe operation: a main discharge connector (not explicitly specified but typically XT60 or XT90 for drones) and a 4-Pin JST XH connector for cell balancing during charging.
