I'm trying to get some answers in this form but so far it is sort of information overload.
The diagram that wesnewell attached for you showed how you can wire an 18S 5, 10, or 15AH pack. The 1-to-3 wire 3-legged black and red wires on the left and right sides would go to the controller on one end and could have 4mm plugs on the other battery-side ends. You connect a set of 3 series-connected packs to 1, 2, or all 3 of these plugs on each side depending on the AH you want. Bottom layer of 3 series-connected packs only for 5AH, add middle layer for 10, add top layer for 15. You can vary voltage by using 2 or 4 series-connected 6S packs instead of 3 in the layers. Sorry if I'm telling you something that's already understood.
