Description
The Crocks Pack Molicel INR 21700 P42A 11.1V 8400mAh 3S2P 80A/100A Discharge Li-ion Drone Battery Pack
is a high-energy, high-current lithium‑ion battery pack optimized for drones, UAVs, and RC applications demanding both endurance and power. This pack is composed of six genuine Molicel P42A cells arranged in a 3S2P (3 in series, 2 in parallel) configuration, giving a nominal voltage of 11.1 V and a total capacity of 8400 mAh.
Rated for continuous discharge up to 80 A and capable of peak bursts up to 100 A, this pack easily handles aggressive throttle changes, fast accelerations, and high-load maneuvers typical of racing, freestyle, or long‑endurance drones. The Molicel P42A cells are known for their low internal resistance (~10 mΩ AC) and high current capability.
Physically, each P42A cell has a maximum diameter of 21.7 mm and a height of 70.2 mm, with a typical weight of ~67 g. The combined pack, excluding wiring and connectors, weighs in the ballpark of 400–430 g, depending on build specifics and assembly.
A 4‑pin balance connector (JST‑XH or similar) allows for safe and precise balanced charging, while a reliable high‑current discharge connector ensures stable power delivery during flight. The pack’s rugged build and efficient design make it suitable for competitive FPV racing drones, long-range quadcopters, aerial photography drones, and other high-performance RC setups.
With its premium Molicel chemistry, this 3S2P battery pack delivers a robust combination of high capacity, strong discharge ability, and long-term reliability — making it a top choice for drone pilots who demand both endurance and power.
