I’ve been trying to figure out how i should wire my 18650 batteries together to make a 12s3p configuration. the only problem is i cannot find any info on how to wire the balance leads or how to group the cells/determine where the pos/neg sides get soldered to. every video or instruction is either a ebike battery or not 12s3p or even 12s4p and its hard to tell where the person is soldering what to when they are making an ebike battery. can someone help out with a diagram as to where to wire/solder and orientate the pos and neg correctly. i understand how to put the BMS together but not how to organize the cells in a flat manner, then solder.
thanks ahead of time!!!
