I have suddenly NO MORE BRAKES

Simplify? Get one bms setup known-good then move on?

That’s obviously what I will do, excuse me man to try easier way to repair my battery, if i can try something before replacing the BMS i will do it.

I would definitely do the obvious thing then and get rid of all the unnecessary complications (multiple bms’s). One thing you don’t want is an unsafe eboard. They’re crazy enough as is and with only one BMS. :wink:
