Hi, Just an idea ... i was thinking on gost loads on BMS, especially when your BMS use a mechanic relay switch on a decent size array on a mobile application. In my case 1000w solar array. Will was talking about the fact that if you have a new balanced lifepo4 pack it takes a bit of cycle to go off balance. So i was thinking what about have a diverter and, especially when you are not using the system, you just bypass the BMS altogether.
Contest: in an application where your inverter/charger (victron multiplus) controller have overcharge and undercharge safety feature, where your 24 and 12 V loads have a low battery disconnect and your MPPT is smart enough to not wreck your battery..
PS you have to take out power to bms controller etc, drawing is just simplification ..bypass bms small.jpg
