I'm in the process of converting my 1959 Zundapp Bella 154 to electric, it originally had a 150CC 2 stroke that was pretty anemic. 7.2HP at 4700 RPM and 8.82 ft/lbs of torque at 3350 RPM. I'm close to 200 lbs and the bike has a heavy steel frame and steel sheet metal body so it really couldn't keep up with modern traffic. I don't plan on riding it long distances, just to the grocery store and the local pub occasionally so don't need much range. I managed to fit 8 Leaf modules in there and have a QS260 12inch 5000W 96V Hub Motor 45H V4 and a Sabvoton SVMC96120 Controller. I've ridden it about 25 miles so far and got it up to 51 MPH / 80 KPH so I'm somewhat happy with the performance, Probably 20-25 miles range. I may add 3 more Leaf modules in the future if I can fit them, I know I can get at least 2 more into it but I'll have to move some stuff around. No BMS yet, that'll come when I figure out if I'm going to add more batteries.
Right now I have a 3S 18650 battery that I'm using to pull in the contactor and operate the precharge relay, no lights hooked up yet. I have a cheap 3 wire DC-DC converter that puts out 12.4V, can I use that to keep the 3S 18650s charged up or do I need to add a charger? Should I just buy a small lead acid AGM type battery and use that instead?
