Molicel P45B 4S 14.8V Li-ion Drone Battery (4500–13500mAh)
DESCRIPTION
The Revogreen 4S 14.8V li-ion drone battery is built on the Molicel INR21700-P45B, a 4500mAh 21700 power cell rated by Molicel for 45 A continuous per cell — the P50B's predecessor, with the same high-current build and a slightly lower capacity at a lower price per pack. The value choice for operators who need real current headroom but not the last 10 % of capacity. Choose the capacity by parallel count and the connector for your current draw — every option uses the same matched-cell build, balance lead and genuine connector, assembled and tested in India.
Best fit: training and drone-school fleets, compact heavy-lift quads and FPV rigs. If you need the last 10 % of capacity and current, step up to the Molicel P50B packs. For a different voltage, capacity, connector, enclosure or a BMS/smart build, use our custom pack programme.
