Once the euphoria of finding and buying the Lithium Polymer battery dies down and rality sinks in, I think I need to redesign the PADD. After a long conversation Kenny, who is a friend of mine, his idea of using a Mobile Phone battery to power the PADD is was good idea. And what's more, everyone has a Mobile Phone anyway. So, its just a case of getting an extra Lithium battery for your phone, charge it and then plonk it into the PADD. That is, until I told him I am going to seal the PADD (ha ha) and this creates more problems. Moreover, no one is going to go out and buy a slim battery and the charger for it.
