    I have been flying the Alta X with a payload of 10lbs and using two Tattu plus 1.0 batteries. I feel like I should be getting at 30 minutes of flight but I have only been getting around 15-16 minutes. The payload is run off of a separate battery and the weight for it and the chord have been added to the previously mentioned payload. Recently I ran a hover test on a day with minimal winds (1-3 knots) and started seeing a decline in performance after 17 minutes with a reading of 44.5v Has anyone else had an issue with batteries dying too quickly?

    What do you mean by a decline in performance?

    Also what is your battery voltage after landing?

    I personally try not let my voltage after landing to be lower than 45v. With the payloads I’m normally flying that’s a loaded voltage of around 44v.

    Flying a 20 pound payload recently I was getting 16-18min.

    how old are your batteries?

    Follow. I rely on Freefly's statements about 33 mins with 10 lbs. payload. I hope this is true.

    I've been playing it safe by landing at 30%. I suspect that the abrupt turns in QGC mapping patterns take a lot of power. I fly mapping missions at 15 m/s. The 90 degree turns are very aggressive at that speed. I'm hoping that they fix the "box turn" issues soon. As it is, I can't get more than about 15 minutes of flight time. I'm using a Sony A6000 on a Grimsey T3 gimbal. That's not much load.

    I got my flight time at about 20 minutes at 44v with current draw at 60-80amps average. I was hoping to get more flight time as shown in the specs. My payload is 4kg. But my battery is only about 7 cycle, i am hoping after few more flight the battery will be properly broken in and gradually increase the performance.

    Has anyone had more battery cycle and increase in flight time performance?
