Description
The Crocks Pack Genx pro INR 21700 P42A 11.1V 12600mAh 3S3P 190A/260A Discharge Li-ion Drone Battery Pack
is a high-performance Li-ion battery pack engineered for serious drone pilots and UAV builders. It is built using nine Molicel INR 21700 P42A cells arranged in a 3-series, 3-parallel (3S3P) configuration. This layout delivers a nominal pack voltage of 11.1 V and a large capacity of 12.6 Ah, providing a balance of long flight time and high power.
Designed for aggressive power demands, the pack is spec’d for a continuous discharge current of up to 190 A and a burst or peak discharge of 260 A. Such high current potential makes it ideal for drones requiring strong thrust, such as racing quads, heavy-lift setups, or fast-accelerating FPV builds.
The Molicel P42A cells underpinning this pack are known for their excellent current capabilities and low internal resistance (~10 mΩ AC) Each cell has a typical capacity of 4200 mAh. Physically, these 21700 cells are large (max diameter ~21.7 mm, height ~70.2 mm) and robust.
The battery pack is built with quality balance wiring (for a 3-series configuration) and a high-current discharge lead to handle the large current flows. Mechanically, it is designed for reliability, vibration resistance, and integration into high-performance drone frames.
Key Features
