Did you know the DJI Spark Intelligent Flight Batteries have firmware?  Yes, it’s true.  I guess that’s why they are called “intelligent”.

Be sure that your batteries have been charged to at least 50% (preferably fully charged) and do this at home so you don’t have to update in the field. Also, do not turn off either device’s power or exit the app during the update.

Hi PardzFilm, thanks for the tips! If you need any help, please feel free to contact us. Cheers!

It is anyhow not a good idea to turn off the device(s) during FW update..
