One of the three flight batteries that came with my Phantom 4 did not function at all. I contacted support and followed the instructions for sending the defective battery in for repair. I was impressed with how rapidly DJI sent a fully functional battery even though it was during the busy holiday season. By going beyond my expectations in this service you have not only repaired my battery but you have also repaired my regard for DJI. Thanks.
Very glad to hear everything has been sorted out rapidly.
Thanks for your support, and we're always working to improve service so that you can enjoy it.
