I have a 2012 Izip E3 Zuma and the battery is not functioning. I called Currie and they said that the batteries are not available until June. Is there a 36V 11.4ah 500W battery that I can purchase and replace this battery with it. I took the battery apart and see that the connections can be spliced. Will this work? I also see there is a board in the battery, is this with all the batteries? Any help is appreciated.
