A123 li-ion packs for R/C

I really like that boost box thing. It's basically just a DC to DC converter, but neat as long as it can withstand the current draw. It would be nice if it handled higher voltage though. All you would need is one ~10Ah.14v pack and you'll be able to dial-up any voltage you need.

A few downsides to these cells though. They are kinda heavy, only 2.2 (IIRC) Ah each, and aren't a typical Li voltage so a different charger will be necessary.
