DJIs reply to this that its normal for slight swelling is BS. BOBEC231 is absolutely right. I dont know if DJI is out sourcing there batteries but if so they need to find a better supplier. If DJI is producing there own batteries then the suck at it and its time start out sourcing. In any case DJI supplies the batteries, the charger and the Drone force lands when it determines the battery is low. Basically they force the care of the batteries on themselves and should warrentee the batteries for either a fixed number of charge cycles or time. Personally I found that the batteries on the
MAVIC 2 when allowed to discharge on there own dont discharge low enough for a safe storage. DJI deff knows how to make a killer drone but they are big time lacking in the battery department.
