That's pretty cool. It doesnt quite work with what I've got going on. That said, you might also get some people interested at DIYElectriccar forums. But, perhaps, you're especially targeting ebikes for whatever reason. Might want to mention, do you know how much of the 6.5ah still works? Have you been able to test them?
New to endless-sphere? Notice a lot of signatures recommending Ebike.ca? That's because it's the best place for a quality and manageable, (but still 'real'), first build. Justin is a solid supporter of electric bike development, and a good source of equipment.
My hat off a thousand times to the green people that effectively run this forum. The ES Mods are superb.
