Good BMS for a 6AH 4S LiFePO4 battery pack
Works well. I’m using it with 4 serially connected 6AH LiFePO4 cells in a solar charged battery for a garden fountain pump. Disconnects from charger when any of the cells reaches 3.75V, which seems at the high end of what is expected. Might affect battery life. Disconnects from pump when any of the cells drops to about 2.6V, which is fine.
