Yeah, the issue seems to be that best practices would not use 2 cables. Short of using a fabricated 2 into one bussbar on the BMS I'm locked into branching to 2 wires at some point. I did a test crimp with a pair of 2 awg wires into a 2/0 lug and it looks fine. I cut it and there are no gaps whatsoever. I'll go with a single 2/0 positive cable to my class T fuse and a double 2 awg cable with a single lug on the battery side and 2 lugs for the bms side. The negative cable will be less than a foot long.
