Be VERY careful NOT to leave the cell in there when you hook it up to the USB.

Oh I know lol, I'm thinking I might beable to add a switch or Somthing so I could or do you think no way just play it safe?

Check out DPDT switches for switching between power supplies.

DPDT switch would work perfect, actually you could probably just go with a SPDT...a common USB/batt ground shouldn't be an issue...I keep thinking about making one of these but sooner or later my eGo USB pt batt is gonna pack it in then I'll have some more micro electronics with wire thinner than a human hair to play with...

screwed up the switch nomenclature...

Instead of the female usb use standard 2.1mm female power plug that has an auto disconnect when you plug the male in. When you plug in the PT it disconnects the battery, foolproof and saves putting another switch.
