Welcome to the forum Big Shooter
Am not sure what this is and just did a quick search for it and this all I could find ,
"Check the battery connector inside the battery opening. Make sure it isn't damaged in any way. It can get damaged in a crash. In addition to the two large battery connectors, there are two small pins that also connect to the battery. If they don't make contact, the battery won't be able to talk to the Phantom which will cause the non-DJI battery error."
Now having said your other battery works fine I would look at the terminals in that battery and even clean them to see if that helps .
Hopefully you don't have a dud !
Sorry but that's all I got . Maybe someone else will chime in .
