For those with the H with Real Sense, how much flying time are you getting on one battery?
Usually 14.3vI am getting 15 min max out my batteries. Start them at 16.8 and as soon as I take off they go to 15.9 or abouts. I have Real Sense but I have never used it. I usually stop the flight as soon as I get a 14.6 reading on the battery though. Never did go to the warning phase. What is the threshold to get the first warning vibration on the st16?
I've never had a 20 minute flight. Best I've done was 18 minutes.You can count on a warning at anywhere below 14.5 if you give it high rev. It will start the warning, you can go back to turtle, clear the warning, and get another couple minutes depending on wind. I've got some batteries on the edge and I'm keeping an eye on those more closely. On Saturday, it was crazy windy here so I opted for an indoor test. With my H in my studio and no camera with GPS off, I tried to hold steady altitude for till the first LVC. If you've ever done this you can almost "feel" the battery draining.
For the first 5 mins it's relatively easy to hold steady and not apply much stick. After that, it will sag in power with each passing minute and drop down and need fresh stick input to raise and hold to the same position. The longer it goes, the more you have to pilot.
This behavior is observable in any drone I've owned as LiPo batteries seem to release power in stages. There are some who will keep flying until it can't actually hold up and basically come down in a low power crash landing. Anything past ten minutes on the batteries for the H is in the "take it easy zone" as it can drain down quickly from there in high winds or fast flights or long CCC missions which fortunately will abort (or not so on a critical shot) once the first LVC activates.
The pursuit of mythical long flight times is like expecting your car to suddenly become more efficient in gas consumption because you used a different brand of gas. It's not worth all the anxiety as it's just easier to own more batteries and plan your flights accordingly.
That being said, if someone knows of the magic 20 minute TH battery that will give me that fourth complete 5 min video burst I'm all in.
After many flights on my oldest battery I've not seen a noticeable decline in it's performance...yet. It's the original one that came with the aircraft when it was delivered to me at the beginning of June last year...and It's the one that I managed to get an 18 minute flight to first warning.15 minutes New battery. Drops to 13 pretty quickly. Now down to 10 after about 30 flights.
