Chinese bms wiring ?
 

Swapping in a Chinese bms for my chargery unit

I got the new bms and a bms box from pingeye

I have looked over the 7s installs. I am doing a 14s

I have two larger c- wires and 2 large b- wires
Is it better to crimp these together inside the box and run 1 wire out for each?

confirming the 2 small wires on each side temp sensors?

Re: Chinese bms wiring ?
 

You’re correct, the two C- and B- wires should be joined together to a larger cable. Joining them inside the box may make it too cramped and generate more heat in there. I would join them outside.

The two thin black wires on each side are temperature sensors.
