So I'm beginning to get my traction batteries balanced and ready to wire but I have a question. My batteries are these:
And I have 18 of them that I will wire to make a 30S3P pack (120V 180AHr). The wire in the car now is 2/0 between the battery leads and controller (car is currently on lead acid pack of 96V).
A. Should I run the new batteries in a 5S3P first and then series those together? Or run a 30S and then parallel the strings only at the top?
B. If the jumper length is short, less than 4" long, I should be okay to run a 4 awg wire, yes? My battery studs are M6 and there isn't room to run 2/0. If I split the load evenly across the packs, there won't be more than say 200A peak through each string.
