Hi all. I’m looking to upgrade my battery on my Carrera Vengeance e-bike to something like a 11.6Ah battery, apparently those sort of batteries double the amount of miles that can be covered in a single charge. By all accounts it’s a Phylion SF-06 battery or it looks like a Devron SF-06 is the same one. On eBay they’re going for nearly £520 inc shipping. Does anyone know any uk sellers that stock this sort of battery for a better price? Thanks
