Some time ago when the upgrade first came out I upgraded my firmware and did not have any issues. Today - I had my first hard landing ever, luckily nothing broken but a blade and my ego. The P2 started to fly away and I did a hard command to drop throttle and I am glad it responded after a couple of attempts to "land". Since then I can not get the PT2 software to recognize the battery. When I hook it up it provides an error message saying "tis is not a DJI SMartBattery"....well it is, I have three of them that hardly have 4 cycles each on them. I have tried to reload the firmware and no luck. Any ideas on a fix? Thanks for your help.
