Samsung 50S 4S 14.8V Li-ion Drone Battery (5000–15000mAh)
DESCRIPTION
The Revogreen 4S 14.8V li-ion drone battery is built on the Samsung INR21700-50S, a 5000mAh high-nickel 21700 cell with a silicon-added graphite anode. At around 250 Wh/kg at cell level it is one of the highest energy-density cylindrical cells in production, while still delivering 25 A continuous per cell (45 A with an 80 °C temperature cut). Choose the capacity by parallel count — every option below uses the same matched-cell build, JST-XH balance lead and genuine XT60 or XT90 discharge connector, assembled and tested in India.
Best fit: compact quads, camera platforms, training and drone-school fleets, FPV long-range wings. If you need sustained current above 25 A per parallel group, look at our Molicel P50B packs; for a different voltage, capacity, connector or a BMS/smart build, use our custom pack programme.
