If anyone is interested I have made a battery mod for PSP 2000 & 3000 models that is pretty simple and straight forward. Also included items you made need for the process in the description of the link. All the best gang! :)
@SylverReZ I've never used a disposable, seems like a waste. kinda cool idea tho. It would be nice to have vape built in to a cell phone even. "The iVape"
