Anyone have a suggestion for a 6V reciever pack for running 1S lipo?

I wonder if you could use a couple really small cell phone batteries and wire them together? Most of them are either Lipo or Li-Ion. It could last a long time on one charge. I'm not sure how small they come though.
I hate the idea of using the same old RX's packs that you have to keep on the charger all the time.

You might be able to use a voltage booster like this one:

I'm using Losi's Micro Baja pack- it comes with a charger- all you need to do is add a switch in-line and a receiver plug. It's tiny, and the charger is so convenient! It's 7.2 volt, but all I've noticed in a year of running it is a little quicker servo!
