If it can take up to 13.4V (it's likely there's a voltage regulator
inside), you can try Lead Acid batteries, like in motorcycles. Very
cheap, but can be heavy.

On the light side, but super expensive, you can try mini model battery
packs, like for RC model planes. 3 cells batteries will give you 11.1
volts, 4 cells batteries will give you 14.8 volts.

These will give you about 2 hours :
