DIY UPS - with LiFePO4 battery (part 3/4)

Previous episode: https://youtu.be/9KGemqeXewU

Hello guys,
I finished building the new UPS. It has a LiFePO4 battery and 3 outputs: 5V, 12V and a USB type C with fast charging protocols. The UPS also has a lot of safety features.
This project was complex, so it took a long time to build it and edit the videos.

A big THANK YOU to all my patrons, especially to: Max Rice, Jon Lloyd, Max Bane and Jonathan Jones.
