Has anyone else experienced batteries destroyed by the firmware bug that was supposedly fixed in the latest release? "Major Updates 1. Improved encryption to enhance transmission security. Aircraft and Remote Controller must be upgraded to prevent unlinking. 2. Fixed issue of batteries over-discharging when stored for extended periods of time (over 90 days)." I saw that in the release notes and became worried as my batteries had been stored since last fall when I updated to the latest (at the time) firmware. When I got my batteries out, sure enough, both my TB47s were completely dead. First DJI asked me to send a video showing the problem. Yes. A video. Of completely dead batteries. Ok. Sure. Then DJI support said: We'd like to ensure that your battery is communicating properly with the unit. We would recommend that you attempt to refresh the latest available firmware update for the battery. The firmware can be found on the DJI Website. http://www.dji.com Please be aware that the information provided indicates that the batteries are outside of their warranty period. If the issue does require you to send the battery in for repair, it would not qualify for a warranty replacement. To review the warranty period for all parts related to our products, please review the After-Sales Service Policy, located at the following link: I explained that it was not the batteries that were defective, but the DJI firmware which I was forced to install after the battery warranty had expired. The firmware had caused the batteries to over-discharge during storage, thus destroying them. And, because they were still completely dead, I could not "refresh the latest firmware update." DJI then replied: "Thank you for your response. As your batteries are out of warranty, it would require for you to purchase new batteries. Please click on this link to learn more on this point:" So, basically, DJI required me to install firmware which had a bug that destroyed all my batteries. Then, they told me to go buy new ones. Anybody else experience this?
