I have this bms and it works well, although slightly higher balance current would be nice.

The b- goes to your battery negative, c- is charger negative and p- is if you run through the bms but I think you said you aren’t so just leave that one. The balance leads should be numbered 1-11 so they just need to be connected sequentially starting from the 1st balance lead or the one on the negative of the battery.

Also make sure to connect B- before the balance leads or it can fry the bms

Thanks alot

@pat.speed There are only 10 pins on the balance connector which are marked b1±B10+. If you look at the pictures there is a small thing marked gnd on the left that doesn’t have a pin. Do I need to run a negative wire to that>

Ahh ok my mistake this must have been the bms that had only 10, sorry I thought it was my other one. You don’t need to run the pin to ground as it is already connected through the b- connection, just number them normally skipping the 1st pin
