There's no easy answer.Would it be safe to fly after a fully charged battery has sat idle for a few days wherein the battery level has gone down to 95%? What actually is the minimum battery level for taking off?
I think it would be fine. It's safest to stick with best practices though. Charge your batteries the day before or the day when you plan to head out to fly.
Personally, I'd rather top of the battery too many times than potentially lose my Phantom.
There's no easy answer.
there is a point where using a partly discharged battery isn't safe.
It's easy enough to top it up and fly with a full battery.
If you have 50% showing for your car fuel tank, you have 50%.Can you elaborate on the safety issue?
Of course I wouldn't fly with only 20% remaining charge (lipo discharge rate starts getting pretty steep at this point) but 90- 95% is easily enough for a still reasonable amount of flight time.
If you have 50% showing for your car fuel tank, you have 50%.
The battery indication in the app is not the same.
At 95% it's probably going to be OK but at some (unknown and variable depending on conditions) level it won't be OK.
It's safer and so much easier to do as DJI recommend and only fly with a fully charged battery.
Making a few short flights is very different from flying with a battery that has been sitting for a few weeks and is showing 60%.Unfortunately sometimes I don't have that luxury when travelling and making a few short flights on the same battery. Common sense and prevailing conditions should tell you when to stop!
