I just bought a new DJI battery for my P4 Pro and tried it out indoors without props just to check it worked OK. I use Litchi most of the time so was using that and it all looked good and no error messages; it said that it had had zero charges and all the data about cell voltage seemed good. I have read that one needs to update the battery firmware when using for the first time so was wondering if this is really necessary as I hate dealing with DJI Go app and don't want to update it if I don't have to as the drone works just fine. Would Litchi give a warning if the battery needed updating? I am on DJI Go 4.26.
