All the PTs I've seen are either direct USB-to-atty, or have a 10440 battery in parallel. The battery ones, if I understand them correctly, basically use the batt as a big capacitor. They trickle-charge the batt constantly at low current, then when you take a hit, it pulls power from the batt instead of from the USB port.
My question is, does anybody make one that uses a 510 batt instead of a 10440? It seems like this would make a LOT more sense, as it would allow you to use it as a PT while charging your batt at the same time. Does this exist? If not, is there any reason why it couldn't?
