Yes, well sort of...You could use a boost circuit, you could use one 14500 Lithium cell, or you could use three 2/3 AA NiMH cells. The NiMH option is the best in my opinion. If you don't feel like ordering 3 NiMH cells, just look for a cordless phone battery that has three 2/3AA in it. (It should be about 15mm thick by 42mm wide by 35mm tall)

I agree, it's much easier to find a battery(s) that you can live with rather than trying to make a boost circuit.
