Description
The Crocks Pack Molicel INR 21700 P42A 11.1V 16800mAh 3S4P 184A Discharge Li-ion Drone Battery Pack (Triangle)
is a high-capacity, high-current Li-ion battery pack tailored for high-performance and endurance drone applications. The pack comprises twelve Molicel INR-21700 P42A cells configured in a 3-series, 4-parallel (3S4P) arrangement, delivering a nominal voltage of 11.1 V and a hefty 16.8 Ah capacity. This design ensures long flight times while maintaining the ability to handle very high current demands.
The pack is rated for continuous discharge up to 184 A, allowing it to support high-thrust motors, aggressive maneuvers, and rapid acceleration — making it ideal for racing, freestyle, or heavy-lift drones. The use of P42A cells, which are known for their excellent current-handling capability and relatively low internal impedance (~10 mΩ), ensures that the pack can sustain high loads without excessive voltage sag.
Each cell has a typical capacity of 4200 mAh , a nominal voltage of 3.6 V, and supports standard charging up to 4.2 V. Physically, the cells are cylindrical with a diameter of 21.7 mm and a height of 70.2 mm, and weigh approximately 67 g each. nting in compact drone frames.
A 4-pin balance connector is included for safe and accurate balancing during charging, while a high-current discharge lead ensures reliable power output during high-demand flight. The pack design balances endurance and raw power, making it suitable for long-range missions, high-G racing, and custom UAV builds.
