This information is incredibly hard to get from most multirotor makers, because it's always really bad and they don't like to be compared to each other. From the battery size & numbers for this general class of quad I'd guess 15-20 minutes (confidence +/- 5 minutes), although that depends whether you put a camera on or not, and if so what. Our DJI S800 airframes will go to 30 minutes with a full load of batteries, but they are much larger and more efficient.
