    Can I use a 48v 15ah Battery with a 36v 350 w bafang hubmotor

    If it says 36 or 48 it should be able to work with 48. The question is do you have to tell it which battery you are using? Does this system have a graphic display or is it just got some lights? If its got a graphic display have you looked through the menus to see if there is a battery setting? Or look for an advanced menu? Have you tried searching any of the numbers you can find on the controller for some sort of a manual or more information?

        I think it will burn out if it reaches the top speed too high for a long time.

          How much power gets sent to the motor is up to the controller. If the controller is properly programmed (and able to handle a high voltage) you could in theory hook up a Tesla battery pack to your 350w hub motor and be fine.

              Ok thanks for all the info people I have a 36v 350w controller and 350w hub motor with 36v 10ah battery hooked up and the bike runs great so after your comments I'm not gonna risk frying something for a couple MPH. IF I need more speed I'll jump on my 48v 1000w bike that goes 32mph
