Spoiler: It was a good experience.
I have two data points now. The first was when the battery that came with the new P4 was dead on arrival. I sent it back and DJI returned a new one.
Recently in Iceland during a flight I got the "one cell bad" error message. I quickly brought the bird down and changed batteries. Later I recharged the suspect battery and the problem went away. But some folks here on this forum suggested that I not take a chance. Since the battery was within warranty, I sent it to DJI. Today, 11 days later, DJI delivered a new battery.
During this process they kept me updated via email and progress of the case could be tracked on their website.
This was a simple enough case, and the items were under warranty. Nonetheless, I am pleased with the DJI experience.
One nit though: In both instances I knew it was a new battery because I had recorded the serial number. DJI could do better by letting us know explicitly the repair/replacement details.
