I've been tooling around the search results for "charging circuit" and most threads seem to be focused on 500mA+ circuits. I know there are box mods out there with USB charging circuits in them, but I'm coming up empty so far on finding info on them.
Anyone have a good source of info for a circuit that will fit in a 2xAA box mod and charge 14500's?
