Inside a classic cheap jump starter
Added 2022-06-20 05:36:23 +0000 UTCThis is the unit I showed in one of the live streams. I got it to check out internally for consideration as a compact high current power supply for costume lighting where it will need to supply 12V at fairly high current for a short period of time.

It's a logical enough approach with modules for charging and protection of the cells, plus a 5V supply option powered by a conventional buck regulator.
