Q) Does the PSP work when connected to the charger?

If the answer is yes then a safe approach would be to use a DE-SW050 run from a 2S (or 3S if you like) lipo as the input and connect the 5.0V output to the PSP via the charger port. That would presumably let you use the PSP and when you are done, still have a charged internal battery.

This approach leaves manangement of the internal battery to the PSP which eliminates most of the potential safety/damage concerns.
