Planning and simulating a flight
If any of the cells is unbalanced, its associated LED will flash red during charging
until it is re-balanced. Charging can take up to an hour, depending on the charge
level of the battery and the required cell balancing work. See the eBee Extended
User Manual for more information on maintaining your drone’s batteries.
If you plan on performing a flight away from an Internet connection it is useful to
preload map tiles by selecting ‘Download maps...’ from the File menu. More
details on how to take advantage of the various map sources available in eMotion
can be found in the eBee Extended User Manual.
