You got that a little backwards. it's 86 groups of 5 cells each.
Are they grouped across parallel lines? I define a "group" as one set in series
, 86 cells in series..... Each cell is 3.7v, and 86 of them wired in series gets us 318v total. Then there are 5 groups of those in parallel to support overall current (amp) flow & power needs (power is volts x amps).
Seems like in balancing, you want to get each parallel path (5) to have same voltage. Then, the sum of cell volts in each series set must be the same as the other 4.
Are you saying there are 86 modules, each with 5 cells, wired in stackable series? That would be the other way to define a "group" and would make sense if they package them that way. Have you opened one of these up?
