Battery Charger & Protection & Boost 5V or 12V
Why people recommend it
Used as a design starting point for a single-cell charging and boost circuit from Electronoobs, with people following it for their own power boards.
Watch for: Covers 3.7 V cells, not 2S packs
In their words
I also found this YouTube video from Electronoobs on battery charging and boost converting so I followed along for my circuit design.

This [video] also seems to only handle 3.7V
