Hi there, hoping this might be the place to get some advice, I ordered a new Panasonic battery for my flyer e bike from eBay but he has sent me a 26v battery and my bike is used to 36v one (I want a spare so I can do longer distances) it's going to cost a fortune to send back so wondering if I can try it out, the manual says the 26 and 36v are different, don't want to risk damaging it by trying? Is that likely? Advice welcome!
