BYD 24V LiFePo4 Battery Modules

Do this across all the cell groups. Connect all your - together, then all your 1+\-2 bars together, then all the 2+\3-... all the way up to all the positive terminals.

Be super careful... or your ring lug will turn into a spade.

Edit: i had occasional connection issues, lock washers are suggested.

Awesome! You spliced the BMS cell leads.
Thanks for the tip!

Did you find a solution to your setup?
I have 14 BYD modules and would be more efficient if I can use one BMS for each 2.
Thanks!

Here was my solution, I paralleled each module using 10 gauge wire and attached each cell to its group by a fusable link that pops at ~100A. The BMS and balancers are attached in the middle of the stack so resistance differential was minimized.
