This is my electric skateboard project.
The battery is made from 64 lithium ion 18650 cells. Since these cells were from old, possibly damaged, laptop batteries each cell needed to be tested and have its capacity recorded. I estimate over 200 cells were tested to find the 64 usable cells
Recycled 18650 lithium ion cells from old laptop battery packs. Assembling in a configuration of 8 cells in series and 8 cells in parallel. Producing 33.6 volts (max) and 16 amp hour capacity.

Electric Skateboard
Description:
​
This was one of my most time consuming projects I ever tackled, but it was still fun. It started when I acquired a large amount of "bad" laptop battery packs and needed something to do with them. Even though the battery packs were considered to be bad there is the potential for some of the cells inside to be in working order. After some thinking I though why not put them on a skateboard with two 2700W brushless DC motors.The end result is a skateboard that can reach a top speed of around 27mph and cover a distance of more than twenty miles.
