Update: Made a quick edit of cory149's OS Pandora Battery Tool v0.6 for this method, You can no longer backup, restore the eeprom, or create an auto boot battery.
You do this at your own risk!!
Never dump the serial, make a normal battery, or Pandora. Nothing else.*
The only time your Slim battery should be in a Fat PSP is in service mode, With the A/C adapter plugged in*
To boot a Fat PSP with a Slim Pandora battery:
- You need the A/C adapter plugged in.
- Plugin the A/C adapter.
- Insert in Pandora Slim battery.
- Remove as soon as you are at the service mode screen. (ASAP)
To convert a Slim battery in Fat:
- Enter service mode with your Fat battery, run cory149's battery tool.
- Agree (Press X) (A must)
- Convert your Fat battery to any other mode, so the convert to Pandora option is shown.
- Insert the Slim battery.
- Make sure the charge light is on (IT MUST BE FOR THIS TO WORK)
- Convert it and remove ASAP.
The what if?:
If the charge light does not come on, or you create a dead battery somehow, just plug the charger into your slim and the Battery, turn all power save settings off, and wait. (The screen never goes off, and CPU set @ 333MHz) After a few hours the Slim battery will charge. I have never fully killed any Slim battery.
The making the Slim battery fit:
To fit a Slim battery in to a fat like in the video, you need to cut off the pegs from the bottem of the battery as shown:
The how does this wok:*
This works because you never should keep the slim battery in a Fat PSP for more then 30 seconds. Never Have the Slim battery in a Fat PSP then Plug in the A/C adapter.

For the person that posted how to fit the battery (As soon as I find the post, I will add them)
Ignore the tape on my Slim battery. I opened the battery at one time to see something. It is not hard modded. If you need more proof, ask for what you want to see in the video and I'll make one.
Added a better video (Video #2)
