    Hi,
    First glitch ever. This morning my P3 landed where it was with a battery warning. I took off a minute ago with a 3/4 full battery, and was so surprised that I watched it landing by itself rather than checking the screen. Once landed the battery was still showing 3 led out of 4.
    I changed the battery and flew it again ok.
    Once back home, I locked the P3 on the bench and started it ok, but as I was revving for 10 sec to 15 sec periods of time, the battery level started to go orange on one or 2 cells, ending up red on all cells and cut off the phantom completely.
    Once back on, everything normal, but as I started revving again, it cut off again quite rapidly... I estimate that I couldn't rev max for more than 15 secs.
    also the temp climbed to 51c/124f.
    Times charged:10
    Low batt warning : 30%
    Critical :10%
    Any comment about this? Because it looks like if I was to do that in flight, Adios muchachos...
    Thanks

    It sounds like one of the battery cells was very low. You can upload your TXT flight log here to verify.

    Ok, I tried another battery, that I could put it on its knees the same way. It seems that my testing method is not adequate. So ti doesn't mean I have a problem or not with the battery. No idea and quite worry as I have a job coming shortly...

    Thanks, done that now, but all what I see is my height and distance. What about the rest? I clicked on Download the CSV, but nothing happened. Any idea?

    My log viewer cannot convert DAT logs. Try DatCon.

    I'm not sure that locking the Phantom down to a bench or whatever, and rev with props on is ok to do. Seems like you will overload it.

    I think you are right on this. Also, I never heard it revving that high when in flight. It is probably not a good idea.
