I recently did an IMU calibration and while I had the v2+ hooked up to the laptop, I checked other tabs (RTH, battery, etc). Now the battery that was in the quad now shows damaged cell warning. I really don't believe there is anything wrong with the battery. It was full so I hovered it in ATTI (because I had nothing but red blinking led's) for about 18-20 minutes to drain the battery completely and try a fresh charge. Same outcome although retrying turning on and off the battery many times I did get it to go through the light sequence and got green sat lock a couple of times but when I tried to lock into wifi fpv, the warning would pop up and go into red blinking led's. Sooooo what now? I've included attachments of the battery condition...not sure but seems fine to me, maybe one of you see something I don't....any help to would be appreciated....thanks!
