Finished building my 25mph Ebike

[JERRY2KONE]

Where is the cheapest place to purchase A123 cells. Their site states that they only do large volume business and do not deal with individual projects like cars or e-bikes. I think that may be our best bet for setting up an E-bike configuration and keeping the overall costs reasonable. I want to make sure that I end up with the power required for such a setup, but also enough capacity for a good long ride. So is there any place special that gives good deals on A123 cells that will fit the bill and maybe a discount as well. Not sure of exactly what I would need, but with a little research I am sure that I can figure it out. That motor kit recommends at least a 48volts, 20amp setup which I would assume means 20,000mah, right? I wonder how long of a full power ride that would give on average if you were to put together say a battery pack 48volts with 20,000 mah capacity? Doing the math on electrical stuff is not my best atribute. I see that they have more indsutrial battery packs already made up that would be awsome, but the cost of those would easily be $1000 just for batteries. Hardly a budget project.
