Litchi waypoint critical battery level question

[jmagee]

As I understand it, if you hit the critical battery level partway through a waypoint mission, the bird will land wherever it happens to be, and you might never see it again.

With this in mind, can anyone suggest a maximum mission length, in minutes or in distance, that you can fly from a fully charged battery, and have a good safety margin?

When you hit critical battery, the AC goes into autoland. Doesn't matter what app you're using or what kind of flying you're doing.

So flight time would be the same as with a normal flight. And that, of course, would depend on your aircraft and the condition of your battery.

Difficult to mention a liable value in minutes.
Rather than the battery condition wind condition might have a bigger impact on flight time.
My personell limit is set to 15 minutes in moderate wind conditions.
