Molicel P50B 8S 29.6V Li-ion Drone Battery (5000–20000mAh)
DESCRIPTION
The Revogreen 8S 29.6V li-ion drone battery is built on the Molicel INR21700-P50B, a 5000mAh 21700 power cell rated by Molicel for 60 A continuous per cell with an 80 °C surface cut-off — the highest sustained-current 5000mAh cell in production. Use it where the airframe pulls hard: heavy-lift, spraying, VTOL transition, high-throttle FPV and any mission where sag under load decides flight time. 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: 29.6V heavy-lift and spraying airframes, mid-size VTOL and long-range FPV. If you want the lowest price per pack with the same build, see the Molicel P45B packs; for endurance flying at lower current, the Samsung 50S packs give more Wh per rupee. For a different voltage, capacity, connector, enclosure or a BMS/smart build, use our custom pack programme.
