Description
The Crocks Pack Molicel INR 21700 P42A 11.1V 12600mAh 3S3P 115A/140A Discharge Li-ion Drone Battery Pack
is a premium high-capacity, high-discharge Li-ion battery pack designed for demanding drone applications. Using nine Molicel INR 21700 P42A cells in a 3-series, 3-parallel (3S3P) configuration, it delivers a nominal voltage of 11.1V and a total capacity of 12,600mAh, providing a perfect balance of flight time and power output.
This battery pack supports continuous discharge currents up to 115A and peak currents up to 140A, making it ideal for high-performance FPV racing drones, heavy-lift quadcopters, long-endurance UAVs, and other RC aircraft requiring high-thrust power. Its robust construction ensures reliable performance under heavy loads while maintaining stable voltage during demanding maneuvers.
Each Molicel P42A 21700 cell features very low internal resistance (~17mΩ), which minimizes voltage sag under high current draw and provides consistent power delivery. The pack comes with a high-current discharge lead and a balance connector for safe and efficient charging, ensuring long cycle life and maximum performance.
