DIY: Salvage high discharge 18650 cells from Makita tool battery for free

This is the entire salvaging process of a Makita power tool battery. These are high discharge 18650 cells and you can basically power anything with them. The sky is the limit. Actually the sky is not the limit as you can fly a drone with it, too! Here are some other videos where I used the batteries for:
1. Quadcopter: https://youtu.be/G-g2D4eJaqY
2. RC car: https://youtu.be/JIGq0A-NQxQ
3. Plexiglass cutter: https://youtu.be/GnWTmmhZVD8
