This is a Li(NiCoMn)O2 battery that I bought from GEB in China, but have decided not to use. It only has a few cycles on it, and I've had no problems. The BMS is built in, and it has balancing, LVC and HVC, although I've never tested the LVC. The charger is a simple plug and play 5A/500W charger that can take this battery from fully dead to fully charged in 3 hours. It has worked flawlessly for me.
