Pandora Battery, which can be used?

Hello

I like to create a Pandora battery but have problems to find original Sony batteries here in Switzerland.
I only find some "Dragon Max 2" model here, can that one be used?

Thanks,
pato

maybe look up a guide i forgot the url but it shows u the compatible battery's

ummm do you have the original sony battery that came with your psp?

Yeah still have the original one, I guess I'll use that one then.
Or if somebody finds the link to the tutorial :)
