I understand its safer but I basically want to just have it wired in like a balancer that I can turn on when I need it. Over 99 percent of the time I want it so it will be off and completely disconnected from the battery. I was just wondering if disconnecting the ground will basically stop the bms from receiving power so that it’s not as dangerous. Also, when I’m riding I will switch the bms off because I’m using my esc for low voltage control and its connected as a charge only bms anyway. I would rather have a bms that I can turn off than a balancer because I will have a small flip up part on my board where I can charge it, turn the board on, or turn on the bms. If I used a balancer I would have to have wires dangling our or I would have to completely open up the board to balence it. So I was just wondering if disconnecting the negative lead would actually do anything?
