Thanks John,
Appreciate your help John and look forward to learn what the battery temp was at the end of the flight and what the ambient temp was when you where flying. I will from now on keep a good check on the battery temp when it is warm outside and see what the flying time was when it came up to 40 deg C. The cost of these batteries are too high to play around with. I get an average of about 22min in P mode, but not pushing the right stick at full throttle. That is with a warning of RTH at 25% battery left, which I follow. I still think it would have been nice to have some warning when the battery temp gets too high in case you do not keep a good look at this every time. But I guess that is the job of the captain.
Cheers
Hi Tony,
did some testing today. Aproximatly 20 min flight, battery drained to 19%.
Had to wait a couple of days, since the last couple of days we had some overcast and the temperature didn't go over 26 C.
Today is a warmer day. Blue sky, 32C (in the shade of course), dew point 26 C, humidity 74%, 4 km/h wind (it's called here Land below the wind). The tropics at it's best.
Had the drone warmed up a couple of minutes to avoid condense. When your in the tropics, you have to let your gear warm up, drone or camera. The devices are chilled by the airco's inside the house or car. Your electronics get wet, your lens damps because the high humidity. At night humidity goes to 97% or higher as the temperature drops to 25 - 26 degrees.
After the flight, got a low battery warning, no other warnings of overheating, the temperature on the bottom of the battery reached 49 degrees Celcius. On top it reached only 39 C.
Hope you got an idea what to expect, visiting the tropics.
Cheers. |
