Is this a stupid idea?
So, it seems that in the disposable 510 kits, the charging circuitry is built into the battery rather than the charger. Is there any chance that circuit could be cannibalized for use in a box mod, say to charge a 10440 or 14500, via a USB cable? It's probably way beyond my skill level anyway, but the circuit in there has to be tiny and easy to fit into a mod.
