I was flying this morning and after a few minutes, this battery gave me a "damaged battery warning" so I immediately brought the craft back and swapped it out. I didn't get any warning with the other battery. As you can see, the battery hasn't been used much. This photo was taken at 78%. Does the voltage make sense for 78%? The first cell is also much lower than the others but I'm not sure if its enough to be concerned. I have the craft idling to see if anything happens but so far so good.
