Pandora's Battery with PSP slim?

Hi, I've read through several pandora's battery instructions/tutorials and the faqs, but I still have this question.

Can you make a pandora's battery that works for a fat PSP by using a PSP slim with the custom firmware with a regular sony battery? (the same battery specified in all the instructions)

(Because I have a regular fat psp but my friend has a slim psp with custom firmware and I just recently purchased the extra battery and memory card)

You're gonna have to use the older battery, and it should be made in China

yeah i have that, im asking if i can use that in the custom slim to make the pandora's for my fat psp

yes, if you make a pandoras battery, using a slim, or fat "pandorable" battery, then you can use it in any psp system up to date. I believe that is what you need to know? I used a fat battery in my slim.

I used a fat battery in my slim.

Is it hard to fit it in the PSP?

no goes in very easily..

its hard to get out though! haha, just use a screwdriver or something and pop er out.

can you still fit the battery cover on it tho?

thanks for letting me know jarett :], i was just worried cuz i didn't wanna try it and then mess up my friend's PSP

can you still fit the battery cover on it tho?

nope.

I need help again.
Got to step 15 following every step with the correct directions and everything.

Searched around but cannot find the solution to this... after Step 15 and attempting to install pandora firmware through Game memory.

You on a CFW psp or one an official one?
You ned a psp that can run homebrew in order to make the Battery.
