Battery connection to the center board has failed. Here's what happened to me on a TB47. I plugged the fully charged TB47 battery into the Inspire 1 and it immediately turned on and started beeping, the gyro spun up and the tail light was flashing red. This all continued as the top of the battery began to get very warm. I had connection to the transmitter and the camera was functioning then the following appeared on the DJI application on my ipad "Battery connection to the center board has failed". I tried to upgrade the firmware but the text file kept coming up "failed". I removed the top of the battery and disconnected the cable in an attempt to reset the battery controller board. I left the cable off for about 5 minutes put it all back together but it did not help. It looks as though this is a factory return/exchange if you are experiencing this error on one of your batteries. There is an issue on the battery controller board.
