In my un-scientific testing, I got 8 minutes, easy cruising 2.5 miles out and back with 15mph wind - last couple of minutes were huge pointless power loops and some amateur wannabe freestyle with a DS SeekerXL.
Compared to Zeee 1300mah and Ovonic 1850mah - the Quad Gas are the perfect balance.
Lastly I really don’t know tech about batteries other than in most cases higher numbers are better (except for weight)- these are similar weight to the Zee and Ovonic but feel much more responsive…or make the quad feel lighter and ready to scream! Love em 👍🏻
