Not to knock you or the project, but... I don't think you're going to find the fun that will inspire you to keep going with that setup. Or maybe you will, dunno. Four tired lead acid starter batteries aren't going to give much range with a brushed motor, keep that in mind too. I don't know how far you want it to go, but I can't imagine that setup being good for more than 5-10 miles TOPS, and you'll be charging for a long time with it.
My own conversion plan uses LEAF battery modules, I have them laid out in four blocks of 4 that I can connect in series to keep current demands down. BMS, good sine wave brushless controller, I'm hoping to see a good 70 miles highway range so I can commute to the office and back on a charge. As a side effect of the layout it'll end up looking like I stuffed a Goldwing engine in a Nighthawk, if I fab up some covers.
