It’s a lipo charger with load sharing The first version is working but make an error with the implement mosfet and the connector names
New version V2.0( not tested) update yes it’s working ! of my lipo charger. Change the mosfet implement error. Change the shunt implement on the bottom. Add DIP switch from TE Connectivity
