If I remember correctly the PS2 Slim's power does not go to a regulator so I think 9v is the max it will take.

But you can use a standard 7808 regulator to get 8v.

Or you can get a certain Revision PS2 slim that runs just fine on 7.4v

thank you, can you give me a little tutorial to solder the 7808 regulator on the system please ?
And can you confirm me that this battery work with the ps2 slim ?

Yes, but you'll need 3 of 'em. The second is bigger but will give you 1.5x the life, and you'll also need an 11.1V protection circuit and smart charger.

Okay thank you for this information
Can you show me how I must use the 7808 regulator please ?

Can I use this DC-DC regulator Module to use 3 Li-Po 3.7v battery, so 11.1v on ps2 slim (8.5v) ?

I don't think it puts out enough amps.
