Most of you guys know my eScooter by the name of "eBike with no pedals" But here is a question about wiring: I want to change the dead batteries to the same voltage but different Ah, from 12Ah to 35Ah, I got the batteries through eBay, Mighty Max Battery from Viet Nam, The new battery posts have holes for 3/16 bolts that came with the Batts, "Do I need to change the wire size"? I have 36 Volts and 35 AH now?
You shouldn't need to change the wire size going to the controller. Your controller will limit the amps and volts for your motor. Ride it hard and see if they get warm?
Now that we are back on track, this is what I am thinking about buying? A little over kill but I would feel safer, 4 Awg size wire and 3/16 terminals with heat shrink all made up? What do you think??? Ohhh 4Awg copper cable is about 1/4 inch of copper...
