I could be wrong, but I think you simply would leave off the last COLORED wire. Then, do the negative at end. It will simply read 0 on that register. Look at diagram for ? to sixteen etc BMS, and copy wiring philosophy.

Just message them on Aliexpress that you want the 12s version, they will make it for you.

Hi, For charging, 13S charger should be used? or 12S charger?

yeah I came to say the same thing, I recently messaged an AliExpress seller about this and they said to just ask them to modify a 13S one for you

i’m guessing 12s or you might overcharge
