I received my JBD 7S-20S 300A contactor BMS yesterday.
It has dual 4AWG wires on each connection. I'm only expecting 200A at full load (fused at 250A). I may end up having to replace the black wires off the contactor if it won't reach my bus bar I'm using to join two packs together, or if the lug size is correct for my bus bar. If I need to change them out, they'll be to 2/0 wire.
For the cell balance leads, this is the wiring diagram given for a 16S pack. I'm supposed to bond multiple leads together. I was thinking of crimping or soldering them together to a single lead that goes to the ring terminal to the cell, but is that ok to do? What's the recommended method? Each balance lead is supposed to be the same length, right?
