Your balance wires seem backwards.

If you think of B- as zero, then the balance wires should count up from there, 1-12. So, B-, B1, B2 etc.

Yours seem to go going B-, B12, B11 etc.

oh ok so B12 connects to the first + terminal and counts down so the one closest to - shjould be 1? oh yes i see i messed that up thank you!

Well crap guess i should have asked here first. seems like i might have killed my BMS
