If you mod your PSP is the PSP modded or the battery
The psp goes through a firmware and then a software mod to make it what they call "modded" I personaly have heard of no battery mods besides the LED's and other cosmetic changes, In other words no hardware change, just software. Also please not that there are several different versions of the PSP out there now and not all of them have the same capabilities.
