Can I use a 12v 20A switch with 36v 12A on my electric bike?
I am trying to power my 36V motor on my bike and i don’t have a motor controller or a plan on how to build one, any ideas?
Thanks….. Wait i just got a great idea! All I need is three switches!
S+-S+-S+- If each switch can only handle 12v and the batteries are in Series then I just put a switch in between each battery and flip them front to back so when the individual switches are acivated they are within their correct voltage.
I would not suggest it. While the amp rating is ok (that’s that more critical factor), the voltage is not and that may create more sparking when turning on and off than you want or is safe.
