Hi I'm new to the ebike thing I just got my kit delivered and I'm on eBay looking for batteries. I want to run to 36 volts in series with a switch to parallel so I can switch between distance and power can I do that?
Let get this straight, you want to run two 36V batteries for example 20Amp , then switch when you need power to 72V? In theory yes you could but to be honest I would say no this is not possible. Your 3V controller would probably get fried.
