Well, I ended up taking the battery apart and desoldering and lifting the pin. I've got it working so far. Although when I went to lift the pin, It sparked. Which I thought short circuted the battery. I was bummed....
.... I had began to investigate. I realized when I plugged the PSP into the power cord, Then inserted the battery it began to take a charge. So, Turns out just leaving it charging resolved me proplem. I'm guessing i'm extremely lucky and it only discharge or "decharged" when it sparked. Now it's workign fine and I plan on resoldering the pin and eventually buying a new battery. In the mean time i will reconvert this. Buy the new battery, And switch it back to a PB. Thanks...
