I am sorry if I posted this in the wrong category. I am new and I am still trying to find my way, but I have a question. I a have a TA-810 type psp 1000 that I use to play around with and I felt like finding a way to work the psp without the factory batter. I think I found a very strange way to do it. I used an HTC 1340mah 3.7v battery, but i didn't hook it up to the usual terminals of the psp. I soldered the negative terminal of the battery to the psps but the positive terminal is soldered. I have a pic here. sorry for the low quality. It require that you have the ac adapter or your usb charge mod to boot it up, but you can plug them out when it boots and play. I am not sure how it is possible but it works. I am still looking into getting it to charge and what not. If you know anything or have any suggestions please let me know.
