If each cell is 3.6v then wouldn't a 2s2p "module" be 7.2v?
2s2p gives you twice the voltage and twice the Ah of a single cell.
4 cells wired to give 3.6v output would have all the cells in parallel, a 1s4p arrangement (if the individual cells were 3.6v).
I would say the Leaf modules are 7.2v or so output and if the module doesn't have the mid point of the 2S part of the 2S2P then you will have to treat them as 7.2v cells.
If the mid point between the two sets of paralleled cells is available then you could treat it as two cells in a single module. I.e. you could use a BMS that monitors 3.6v cells.
