Yes, everyone knows how to make a Pandora battery by now. Have you ever thought of making the BATTERY without a second psp? Well, here is the way to do it.

First go out and buy yourself another battery. This is because after you do this your battery will not work anymore. Make sure your new battery says "MADE IN CHINA" since sony is now shipping "un-pandorable" making batterys that dont allow you to convert it.

Next make sure you have some soldering knowledge, and you are on your way. 

Take a look at these pictures and with one soldering of a wire you have now made a Pandora BATTERY without the need of another psp.
