Precisely. I hate the "Phat" PSP moniker, you see. I don't have the PCB in that diagram, mine is the smaller one at the top of the battery.

I had a battery like that, it was the one that came in the box with my PSP...I couldn't find it either, so i just bought a new battery to use as my pandora.  It had the smaller PCB on top, but it has the IC like in the tut, same designator and same value on the IC and everything...If it's not pretty much the same layout of the one in the tut, only smaller, then u need a new battery...

Is the second battery you bought the same as your first? If so, I could just do the modification based on your plans.

No.  The one I had at first was the stock battery that came with my PSP, is that what u tried?  Anyway, the PCB was totally different than the one in the tut, even though the casing was exactly the same as the battery they used.  The second one i tried also had a top-mounted PCB, as opposed to the larger side-mounted one, but this time, the layout was basically the same as the larger PCB in the tut, and it had the IC that I needed, same value on the part, and same designator and everything.  So I'm guessing it's just that stock battery or somethin...can't be sure, is the one u tried, is it the stock one that came with it?  Or one that u bought? 
Anyway, here you can find a pic of my stock battery to compare to yours...

My best suggestion is to just go get a new battery.  I don't see any way to figure that battery out, maybe someone else could, but I honestly didn't feel like scalpeling off all the masking goo they used to cover most of the PCB.  That's why i bought another in the first place...good luck...

Yeah, can you please post a high-quality picture of your Pandora'd battery, so that I can double check the schematics? Thanks

No, I honestly can't.  I tried for ya, but I don't have a camera that'll take a picture of something so small.  i can post a pic, but its gonna be real fuzzy and indeterminable.  Okok, i lied...I had an idea...I put a 5x zoom jeweler's eyepiece in front of my lens, its a bit better, here goes...




The inset pic is zoomed out a bit so you can see where it is on the board...I couln't get a good pic of the pin itself, so I made my own diagram to show you which pin u need: 




I guess it doesn't matter how you count the pins, as long as you get the right one...but anyway, if yours look different than this, and/or has globs of masking goo covering the parts on the PCB, might as well get yourself another one. 

Hopefully I've been some help to ya...if not, hell, at least i know how to use paint alot better now!  lol
