I can wire the balance leads for a 4s bms in my sleep. Pack negative is named cell one. The pack main negative gets the first lead. The every positive in order, gets the next 4 leads. Pack negative then has a balance lead on the pos and neg. The other cells each get only pos.
Some vids on the non-Overkill JDS bms show this configuration
This screen shot from Overkill's manual shows different. I can't imagine this is a screw up. But I can't convince myself to do this.
Pack negative gets the first, then cells 1 and 2 get a pos. Cell 3 gets nothing. Cell 4 gets a pos and neg.
Convince me
