Hi, I have an Air 2 which I love, and I also have recently purchased a Mini 2. Due Lockdown in UK and new 2021 Drone restrictions, I will be using the mini 2 and not the Air 2. What should I do with the batteries (3) of the Air 2, and is there any other advice I need re leaving the Air 2 in its bag unused? (Apart from taking the A2 C of C course)
