How to build a lithium ion electric bike battery pack from recovered used laptop batteries. Save hundreds of dollars by salvaging 18650 li-ion cells from used or even dead laptop batteries bought off eBay.

My pack is 24 volt 20AH which should hopefully provide a 30-45 mile range per charge on my ebike (and cost less than $150 dollars). In the video I show you how to calculate the capacity, then wire and test the completed battery.

UPDATE: The battery had a total capacity of 19aH. The groups of cells were slightly out of balance (3.3v, 2.5v, 2.9v, 2.5v, 3.1v, 2.9v) so I could rearrange some cells and get a few extra miles, but I'm happy enough with the results.

Don't Throw That Microwave Away!
