I own this fellow, Li-ion Power Pack Charger - 2 cell
and the page says it is compatible with
. Oddly enough it should say most batteries over 2000mAH
for I have some in that series, and the thing ignored them. And the site does sell these High Capacity Li-ion Cell | 28987
which the site recommends. However my local store, (not Micro Center!) which is Tinkersphere, sells batteries in the 2500mAH ratings, which are 3.7V Lipo Battery 2500mAh: 18650
And of course matching holders. As it happens the good folks at Adafruit, make and sell a booster rig that translates the output of a single battery at that rating, into the levels that would run a Pi or a Beagle or the thing from Italy. I had originally planned on using either of the batteries to power a Pi Zero W to do something else entirely.
In the advent that the battery holders and the batteries don't work to power the booster to power the Pi, can I use those batteries to run that Parallax rig?
