I finally got the last part needed to build my battery operated Zero in a mint tin. This basic setup was mentioned in The MagPi several months ago, but just as a potential project: they hadn't built it yet. And anyway it's a right of passage to put your project in a mint tin - kind of the hardware equivalent of hello world I guess.
I'm using a 18650 Lithium battery salvaged from a laptop battery pack. According to the Internet, even in a dead pack, most of the batteries are OK. I used batteries from a working pack, so I shouldn't have any problems. I was able to pick up an inexpensive charging and boost module for a couple of bucks from China. Much cheaper than a similar item from Adafruit. And the module build quality is excellent!
