DIY Lithium Ion E-Bike Battery Pack from 18650 Laptop Batteries

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.
