Yes, Phat Batteries can be used in a slim to use as pandora. You can then simply replace your Slim battery back into your Slim PSP and use as normal. :smile:

With pandora there is no need to go back to 1.50, DO NOT attempt to put your slim back to FW 1.50 it will brick your psp.

The Slim cannot run FW1.50

Go straight to 5.00M33 or 4.01M33 (if your using DC7)
