Description
The Crocks Pack Samsung INR 21700 50S 11.1V 20000mAh 3S4P 180A Discharge Li-ion Drone Battery Pack
is a high-capacity, high-current Li-ion battery pack tailored for performance and endurance drone applications. Built with twelve Samsung 21700‑50S cells in a 3-series, 4-parallel (3S4P) configuration, this pack delivers a nominal voltage of 11.1 V and a massive capacity of 20 Ah, making it ideal for long-lasting flights.
This pack is designed for high current draw: rated for up to 180 A continuous discharge, thanks to its robust parallel layout. Such capability makes it well-suited for large drones, heavy‑lift quadcopters, and UAVs carrying significant payloads or flying long-range missions.
Samsung 50S cells are known for their stable performance and good cycle life. According to available cell data, they provide nominal voltage around 3.6 V and have a nominal capacity of 5,000 mAh per cell. Their typical weight is approximately 70 g per cell.Y Despite not being designed for extremely high-current applications (the cell’s continuous rating is modest), the 4P configuration enables this pack to deliver high currents reliably when assembled properly.
The pack is expected to include a balance connector to support safe charging across parallel groups, and a high-current discharge connector to handle heavy loads. Its rugged construction ensures mechanical stability, and using Samsung cells ensures thermal stability and longevity.
