Indeed, 60lb deep cycle battery from costco was just fine for me - I did use 12v to 7.5v converter from Frys to power the pump - I tried running it from 5v USB converter and there was not enough flow in my opinion (this does work as a backup though :))
I only ran the pump during the day of course, but fans were on whenever we had people in the yurt - at least 12 hours a day (I do have 2 fans on my bucket for redundancy).
