Correct me if im wrong but when a battery isn't fully charged it's not calibrated right and registers that the battery is low when it is not. That's why DJI recommends discharging them to 8% and fully charging them every 20 flights.
That's the only thing I can see causing an auto land with that much showing. It seems to be a issue with the drone and or battery not having a data curve ability to see levels as it looks like in the display. Personally, I don't think this is desirable. At the most I think it should only give a warning (Battery was not at critical low level) and the user should be able to decide what action to take. Not force land willy nilly with an apparent "It's got enough for now" battery level indication.
That was my first thought. But he had flown that battery the previous day and just didn't check it when it was inserted. The auto discharge was set to 10 days. This shows the phantoms program cannot properly calculate the curve or similar projection. His critical battery was set to 30% I believe with a RTH choice. It went critical and wanted to squat where it was.
Ok, I don't understand why it would ever be a good idea to increase the critical warning above the minimum possible setting, have the warning level wherever it suits but an autoland being force initiated when yiou just know you could get it back to you can't be a good idea.
I misspoke on critical setting. I meant to say low at 30% and critical at 10%. Which neither of those levels were present. It acted as if 49% was critical.
Without seeing a log file fair guess is significant voltage imbalance issues triggered the critical scenario. Am aware of more than one issue like this with a battery that had entered self discharge.
You can send me the file and I can see what I can do. I'll pm you my email.
