If your unit were drawing 250ma you should get 12 hours of operations out of 8 or 9 lithium AA’s.
The Lithium AA’S are a 3000mAH source the LiPo I referenced below are a 5000mAH rechargeable. So you will only get about 1.5 times as much operations out of the LiPo’s as a set of Lithium AA’s. You will still need more than one of them.

Wow MP, looks awesome. How do I go about getting one? ;D ;D ;D

Have you ever soldered parts to an electronic board? Can you neatly drill holes and assemble small parts in tight spaces? Do you have a car battery charger and can you hook it up through a resistor?
