Introduction: How to Make an E-bike Battery Using "dead" Laptop Batteries.

In this video I will explain how to recycle "dead" or not workin laptop batteries to give them a "second life". With the batteries I recovered I've built a 36v 24Ah battery for my electric bicycle.
Please bear in mind that the "18650" cells used in the video are Li-Co chemistry. This means:

- High energy density 
- Cannot be charged AND discharged  at more than 1C, going over this limit will cause lot of heat to develop and consequent risk of fire/explosions
- never discharge them to less than 3.0volts
- never charge them over 4.2v (stay safe at 4.1)
- Always work in a safe environment
- Use protective equipment if necessary
- Use common sense 

Of course you can use this batteries for other applications, I am just showing you what I used them for.

This work took me a lot of time but I learned a lot and gave me great pleasure when completed.

I hope you enjoy.
