I've been reading this forum recently in preparation for starting my own ebike build, which I intend to power with a 24 volt 350 watt motor. I will be buying a pair of 12 volt 12 ah SLAs to hook in series to make 24 volts. I have a 12 volt charger, so my question is: can I switch the jumper wire(s) to make them parallel and charge them with the 12 volt charger, or should I unhook them and charge them separately, or just break down and buy a 24 volt charger ($17 on eBay)?
I have a pair of old Huffy 3-speed bikes. They have the internal gears in the rear axle. I have put the rear wheel from one on the front of the other and will be mounting a geared down motor from a Razor Dirt Quad over that wheel. A total drive ratio of 14:1 on the 26 inch wheel should give me about 16 mph and enough power for the hills around here, plus it should freewheel easily when I am pedaling with the motor off. That's the hypothesis anyway. I'll keep you posted as the project progresses...
