Yes - "S" stands for series. Packs are often talked about as Series / Parallel. For example, 14S, 2P would be two cells in parallel and 14 in series for a total of 28 cells. Most golf carts are nominal 48 Volts with Lead/Acid batteries. Lithium batteries vary from about 3.3V to 4.2V per cell from discharged to fully charged. If you multiply those numbers by the number of cells in series it gives you the range of voltage of the battery. So 12S is a bit lower than an equivalent 48V Lead acid pack and 14S is a little higher. The Leaf modules I used are 2S2P each so 7 of those in series would give you 14S. I used 14Modules in series/parallel so my pack is 14S 4P which gives me about 120Amp Hours of capacity.
