That battery surely exist and it will give You 4 hours of running using one of them assuming You manage to draw only 2 Amps. Else, at 5 Amp, less than 2 hours of peltier powering.

They are 2 batteries of 9000 mAh at 14v (18,000 at 14v).
If it is at 12v it would be about 20,000 mAh. If the peltier draws 5 amp. it would last about 4 hours of uninterrupted use. Turning off and on about 6 hours, with a single cell.
