[EN] Everything you need to know about power tool batteries

This video answers almost every possible question about power tool batteries. You will learn what do the parameters mean, why do we increase voltage and why more cells is better. I will also break some commonly known lies based on misunderstanding. And I will give some advice for buying packs and treating them properly so they last.
Video is divided to chapters, so you can only watch what you need.

Please apologize my simple english with not that colorful palette of words and shitty accent.
