Finished building my 25mph Ebike

[snellemin]

I build up a ghetto battery pack consisting recycled laptop 18650 size batteries. Total of 13s4p setup. Startup is sucks, as there is not enough Amps. So more pedaling is required. But once you start to roll, it will go all the way to 25mph on a flat road. It just takes longer to get there compared to the lipo pack. Battery pack was at 109F at the end of the trip to work. A 6p pack would do better. I'm running at the max continuous ampdraw of the pack. But now I'm averaging 500W, like the system is rated for.
