Today we received a defective DJI smart battery from our customer. The battery has been discharged 35 times, is 4860mAh full capacity and 89% life left. Only 6 minutes flight time is reported.
Our app log system shows that the battery got a high current draw (~50A) abnormally. That is the reason why there is really high discharge rate - battery level drop 50%-7% in ~1 minutes (1:30-2:30)
