Battery Pack 6s4p Samsung 50S 20000 mAh

The Samsung 50S 6S4P 20000 mAh Li-ion battery pack is designed for demanding FPV drones, VTOLs, and fixed-wing UAVs requiring high energy density and sustained discharge performance.
Its 6S4P configuration (24 cells) provides a nominal 21.6 V and total capacity of 20000 mAh, delivering approximately 432 Wh of usable energy.

Each Samsung 50S cell offers up to 25 A continuous discharge with exceptionally low internal resistance, ensuring minimal voltage sag under heavy load.
The pack is built with copper busbars using precision spot welding for maximum current transfer efficiency and durability. Equipped with XT60 or XT90 connectors and a JST-XH balance lead, the assembly is enclosed in heat-shrink insulation for protection against impact, dust, and moisture.

Ideal for long-range FPV drones, wings, and hybrid UAVs where endurance, reliability, and high discharge capability are critical.
