In trying to register my  Air 2S Assets with Kittyhawk, I am asked for the battery serial numbers. Is there one? If so, where can I find it? *(Numbers I can read are identical on all three batteries )

Hi there, thank you for reaching DJI forum regarding the inquiry. The serial number can be found on the body or on the DJI Fly app when we set it up. It should be under the small QR code and has a 14 alphanumeric combination or on the DJI fly app kindly go to the Settings and under "Safety" kindly look for the battery info, thank you.
