Replace balancingboard in smartlithium 200A

Does anybody has experience with replacing a balancingboard in a Smart Lithium?

I have tried it but distroyed the board. In what order do I reconnect the different wires?

I Have another board from a 200A battery but I do not want to distroy it also.

It came from a battery wich was totally drained so the board must still be working.

Has anybody got advise for me?
