    DYI bike

    New from Ky USA. 1999 stumpjumper 2 48v 40amp lithium on a switch goes between 48 and 96v 45amp controller dd hub motor.

    Sounds fun. What did you use for a switch? Switching between series and parallel is just a DPDT switch but at 40 amps doesn't seem like a common or small device.

      Have been told diesel engines that don't decompress when starting often start on 48v but charge at 24v or 12v.
