Hello--anyone have any advice or experience over-volting an A2B Metro? My original battery croaked and a buddy had a cheap 48v 22ah LiFePo which I tried to hook up to the second battery connector, without success. There are four power pins and a bundle of four tiny wires which do not appear to be connected with anything in the native battery pack. Hooking up the 48v lights up the speedometer but the throttle does not produce motion.
Any advice much appreciated!
