I bought a mini 2 fly combo, the drone has disappeared, now if I buy the non-combo package, can I use only the remote and batteries that I have with the drone?

Hello there cetasule. Good day and thank you for the inquiry. I am sorry to know what happened to your DJI Mini2. You can use the DJI Mini 2's remote controller and intelligent flight battery on your new DJI Mini 2, all you need to do is to check if the firmware of the said DJI Drone and its accessories are all update and link the said DJI drone to the said DJI remote controller Thank you.
