BMS cabling question

[bds70]

The JK-B2A8S20P BMS requires 2 16mm² neg cables on both the B- and P- contacts. Given that should the cable coming off the Pos pack terminal going to a bus bar, also be 2 cables or even one 32mm²?

What cells? Single terminal or dual?

Would you do one lug and two cables crimped?

I don’t like double stacking lugs on battery terminals.

I’d do equivalent cross sectional area single cable.

Single stud terminal on the cells. I can do either double cable into one lug 35-6 on batt end and 35-8 on bus bar end to fit the securing bolt, or dual cable dual terminal at Batt end but still joined at bus bar end. Or 1 single cable. Finding 35-6 lugs seems to be an issue at the moment for me.

Decided to go dual cable 16mm² one 35mm² lug both ends.
Thanks for the help

No, you do not need to match what’s coming off the negative. You do need to make sure you use large enough cable for the current you expect and adequately fuse it, but there’s no need to match the BMS wires on the positive.

I didn't have any have any 35mm² cable but lots of the 16mm² that made my decision for me. Lol
