Get a 12V lead acid motocycle/lawnmower battery.  just cuz there 12V doesnt mean they have to be big :winker: I use some at work that are like 5"X5"X3".  Also could hijack a 12V battery of that size out of a broken computer UPS supply.  I bought a little trickle charger for a 12V battery for $20 the other day.

you could also design it for 9V and use a lantern battery.
