DIY UPS with 12V and 19V (for Asus router) part 1

Hi, guys! I finally finished building this UPS. It has 2 outputs of 12V and 19V and a big capacity, even bigger with better li-ion cells. A lot of you asked me to make it and because you are my favorite subscribers :) here you go!
This is a big project with a lot of details, so I divided it into 2 videos.
