I'm putting together a 12v, 100Ah power box. I want to install a "safety switch" that can turn everything off when not in use. My initial thought is to install a big automotive type battery disconnect switch, but would I want to leave the BMS connected to the battery for monitoring? Another thought might be to put a smaller switch on one of the BMS control leads, that would turn the BMS off, and keep it from connecting power to any of the outlets. Any thoughts?
