Over at acidmods forums, -Neubit- has put up a step by step tutorial on how to get your PSP to run on three AAA batteries.
The PSP battery was opened up and the original battery was taken out, two wires were soldered to the +/- points on the battery circuit board. No resistors were used. The 3 AAA batteries were fitted inside the battery case and connected to the previously soldered wires. Simple enough?
So the next time you're on vacation or out and you're PSP battery is running low, all you need to do is go into a store and pick up a pack of AAA batteries.
