Gregory's Server@mschulkind That's an 18650, significantly larger than AA. Many battery packs are just a bunch of these in a plastic shell. Notably Tesla batteries are just a huge group of them in a shell.

@missed_sla @mschulkind That one is an 18650, however they do also make the 14500, which is exactly the AA form factor, there are actually a lot of flashlights that can take both 1.5v AA's and 3.7v 14500's.
