I hope someone knows the answer. I have a new Levo the 4500 dollar one. It comes with a 460Wh, 40x3.2Ah, battery but I was told they make another that is 504Wh, 40x3.5Ah. I'm told this second battery will also work even though I my bike came with a different battery. I was also told it would give me about 20% more life (not interested in going any faster). They have a black Friday sale going on today so I'm going to go ahead and buy it but if I find out it doesn't work I can return it. Does anyone know if these batteries are interchangeable?
