Finished building my 25mph Ebike

That cheap Ebay kit is better than I thought it would be by a large margin. Awesome setup for those wanting to stay at the legal speed limit. I think the system is just rated for 500W to be considered legit. It actually pulls 700W continuous. It will probably be able to do more with the new controller and better motor wires. Might not even need a new hub after that.

I've learned one thing about lipo's in a Ebike vs Rc. Your batteries are depleted when the voltage reaches 3.7V per cell. Voltage under load is 3.95V per cell. Batteries stay in balance when I leave at least 20% capacity in there. I don't gain much more capacity when I charge to 4.1V per cell over 4.2V per cell.
