I've had an Air 2 since June 2020, but just bought a 2S from a friend, and got 5 batteries with it. He didn't fly it much, so I knew it needed firmware updates. I applied the latest update to the drone and controller. I always thought that you had to also put in each battery to have the battery updated. I tried that, and it did say an update was available. When I went to apply it, it quickly says update was applied. If I try it again with the same battery, it does the same thing.
Do batteries still need to be updated? If so, what's the method??
