Let's get our hand dirty and fix an old power bank. I got this thing a few years ago but recently it died. Li-Ion 18650 cells inside just died and now it even can not do a full charge of a smartphone.
What we will do over here:
- get this thing apart
- solder together 3 18650 batteries I got for cheap from disassembled power tools battery packs
- I will be coughing after inhaling too much of soldering acid fumes
- have a nice talk about a zombie apocalypse, nuclear holocaust, communism and Kapton tape
- get things done!
