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

I think your Vengence battery is about 8.8 ah, so you'll get about 30% extra range, certainly not double.

I'm always on the lookout for a cheap seller of a Phylion SF-06 cased battery, so if you find one be sure to post back here. I think Greenway put these on their bikes

I’ve found a site called insportline.eu and they have a Devron SF-06 for €472 which is about £350. It looks exactly like a Phylion SF-06 and it’s 11.6Ah except it’s black which I actually prefer. Still a bit pricey though so I’ll keep looking.
