Air 2S with DJI RC. Last week I went on a flight, was within LOS, took pics, battery was low, flew back in, swapped the battery. Went out to the same point, my signal was crap, dropping to red, and almost had RTH kick in. Managed to get it back. Put in a third battery, flew to the same point, all was good, no drops at all. I put aside that second battery and looked at it when I got home. There's nothing visual that would tell me that it's bad, no bulging, lights working.
During this flight, nothing in the environment changed... no cell phones, no people, nothing at all. Totally weird...
