Battery for Ps2 slim

i wonder if those pre packaged RC batteries come with a built in protection circuit

Usually they don't. Actually, they almost always don't. Unless it specifically says so, it doesn't. No big deal, you can add one yourself relatively easily. One problem though- the PS2 needs 9V, so you're going to have to cut the power down with a voltage regulator. A PTH08080 should work fine.

Uhhh no a PTH08080 or 08000 will output up to 5v, so 9v = big nono.

Oh right, I was probably thinking of a different part. I know there are similar TI cards that will...
