LiPo batteries charge with a LiPo-specific balance charger set to 4.2V per cell, at 1C or below.
For the full breakdown, see our best 11.1V LiPo Battery guide.
Charged wrong, a LiPo battery can swell, vent, or catch fire. Charged right, it stays cool and keeps delivering full capacity — and “right” comes down to three settings: chemistry mode, cell count, and charge current.
This guide covers how to charge LiPo batteries properly, with the exact rules that apply to standard LiPo packs. The short version: use a LiPo-only charger, set the correct cell count and current, balance-charge multi-cell packs, and stay in the room while it charges.
The Three Numbers That Matter
LiPo charging follows constant-current/constant-voltage (CC/CV) behavior: the charger pushes a steady current first, then holds the pack at 4.2V per cell while current tapers to near zero. To set it up, you need the cell count, the voltage limit, and the charge current.
Cell count is printed on the label as 1S, 2S, 3S, and so on. Each cell has a nominal voltage of 3.7V and a full-charge voltage of 4.2V, so a 2S pack finishes at 8.4V and a 3S pack at 12.6
