Hello there,

I'm making some kind of pi-pad. But the screen needs a 12v input.

Does anyone of you know a small battery which has an output of 12v?

The second thing would be on how to recharge these?

I've seriously looked everywhere but couldn't find a solution.

If you have looked everywhere but didn't find a solution then why do you think a solution exists? :-) .

Does 97 x 43 x 52mm fit your definition of small?  Search for MM22 at maplin.co.uk.  Alternatively you can put 10 NiMh cells in series.  Or use a lower voltage battery and a step up converter.
