Sorry to hear you went thru all that trouble.
One piece of advice , isolate that damn charger from the chassis. Mount it on rubber standoffs, or use nylon bolts, etc. Do not let charger's case contact your chassis. This is primary reason why you keep blowing your BMS boards. Obviously its not related to motor shorting, but it keeps adding up to your troubles.
Manzanita connects its case, which is connected to AC neutral, to your 12V ground ( chassis ), which removes isolation between high and low voltage circuits. Without such isolation, any other conductive path ( salt, wire short, etc ) completes the circuit and blows stuff up.
Oh, and don't work on the car while charging and disconnect the pack from everything else when working on BMS connections.
BTW, since I sympathize with your troubles, I'd like to offer free repair of your BMS boards, you'd just pay for shipping. Send me all failed boards and I will fix them for you.
