Molicel ultra-high power series

The original listing highlights high discharge current, low impedance, fast-charge capability, thermal stability and low-temperature operation down to -40°C as features of the series. Check the manufacturer's cell datasheet for the conditions and limits that apply to your application; cycle life and usable performance vary with current, temperature and charging conditions.

For your build

When planning a drone or other high-current pack, confirm the cell dimensions, current demand, charging method and protection requirements first. This is an unprotected lithium-ion cell, so use a suitable charger and battery-management protection, and leave pack assembly to someone qualified to work with lithium-ion cells.
