You could just buy some Ni-Mh AAs if you want to keep things small. Or just get at 12v lead-acid battery.
I bought one of those blue Li-Po batteries of eBay (security camera battery), but killed it pretty quick by letting the charge get too low. Those are also all way below their stated capacity, and I think pose higher risks of fire than other batteries.
