All Leaf packs are 96S, meaning 96 groups of cells in series. Other than the 62 kWh pack, all Leaf packs consist of 48 modules each with 4 cells in a 2S2P configuration (two cells in a parallel group, two of those groups in series), so all of the modules are connected in series. Other than the earliest packs, the modules are stuck together in pairs (but still electrically separate), so there are 24 pairs of modules that are easiest to leave in pairs.... How many cells are required? I've seen 48 cell packs and... something like 62 cell packs I think. Am I mistaken and they are all 48 cell?
The 62 kWh pack has three different sizes of modules, still connected as 96S, but 96S3P (96 groups of 3 cells each, or 50% more cells of about the same size as the cells in the 40 kWh pack).
So there are no 48-cell or 62-cell Leaf packs. Other than the 62 kWh packs, they all have 48 modules.
