I'm writing up my Orion 2 BMS to 7 Tesla batteries. I'm trying to figure out how to do with the final 7 cell tap wires. The manual says.

"If fewer than 12 cells are populated in a group, unused cell taps must all be connected to the highest potential cell in that group. For example, if 6 cells are populated in a group, taps 6 – 12 all must be connected to the positive tap on cell 6.*"

But, would that mean to connect all the extras to 12, not 6?

Okay, I found my own answer in the validator manual

"If cells are skipped at the end of a bank, all the remaining cell tap wires must be tied to the positive most cell in that bank (A common cause for this fault). " So, I think the BMS manual is wrong, or it assumes the cell taps are sequenced differently - which I don't think works.
