I am trying to build my own battery pack. From my research, I have found that I need a BMS (battery management system) and I have also learned that a battery balancer (like the hobby charger) is a good idea. My question is, does anyone know of an already made item that has both functions of the BMS and battery balancer? If so can you please give me the links? And if not would someone be able to help me design this circuit?
Thanks
James
