I have an E-Joe Anggun. Its about 4 years old now. I was looking into getting a new battery. They dont seem to sell them on the shopebike store anymore. I see a lot of similar looking batteries on Amazon and Ebay but I am not sure if they will work. I really dont want to buy a $300+ battery that is not compatible with my bike. Does anyone know what batteries would be compatible or if there is a place you can buy Anggun battery packs?
