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?
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.
