I have now been able to rack up some km on my new voltbike. Enjoying it very much and learning lots of little things.I have observed that out of the gate with a full charge on the flat I top out at around 38kmhr. By the time I am down to 44 volts I have fallen to a top speed of about 28kmhr. Speed appears to track voltage in a linier way. I started thinking that if when the voltage had fallen down to say 46 volts that it would be nice if I could switch in another // grouping of cells to add 4 volts on demand. Is this a crazy idea, some reason I shouldn't do this? My battery pack is 16amphrs at 48 volts, controller is limited to 15 amps from the pack (but can be set for 20)I thought of building a pack of 6? 18650 cells in //. That should put me in the ball park? any ideas?
