Hello
i have one technical question.

For now i have one battery for mavic air and i just fly once per day.
But battery on controller has much more fly time than aicraft battery and i want to know is it better to charge controller battery on full every time or it is better to charge it every few flight? I have this question because i want to keep battery in good condition

Thank you

I always do but mind you I go through my 3 batteries and sometimes more if the weather permits.

I really don’t think it matters either way, personally I charge my controller every time I charge my mavic batteries.

Charging after each use is probably a good habit to keep.
It won't degrade the battery quicker by doing so.
You will always have the peace of mind, knowing it won't go flat mid flight and will cope with the drain of your phone/tablet as well.

If i have nothing going on and am just practicing i will only charge the RC when it gets below 50%.
