[QUOTE="Starway, post: 498686, member: 32798"] Hi guys, ‘I don’t know if anyone could help but I thought I would give it a shot. I have a ebike motor with a 60v controller that came with it but I have been using a 48v 15ah battery the whole time, the battery is actually 5 years old but I haven’t used it that much so it’s working great still. . I must say it’s working great . I was thinking a few things though could I add a 12v 15ah battery lithium ion in series to get 60v battery output? Would i harm my existing battery ? I have seen cheap 12v 15000mah batteries on eBay designed for cctv systems or various things , could I add this to my bikes existing battery connection and turn it into a 60v like my controller is designed for? Also how far can you push a controller in terms of voltage, as I was thinking maybe I could get a 24v and go up to 72v . Would that be too much for a 60v controller? Thanks guys JAMES [/QUOTE]
