Here, we will take 3.7V 100mAh lithium cells as an example to explain in detail. Part 1. Understanding lithium cell series, parallel, and series-parallel connections
The leads monitor each series groupings only. So if you have a battery that is 10 cells in series and 7 in parallel, You monitor the 10 and not the 7.
Generally speaking, it''s irrelevant how many cells you put in parallel in each cell group, as long as all the groups have the same number of cells at similar capacities (i.e. you do not want to put one parallel group of 3 cells in series with a parallel group of 4 cells), since the BMS will see your parallel groups as single larger cells and ...
