    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.

    Go for deep discharge cycle and check if it recovers

    I think he means, run the battery your having trouble with down to 8%, then let it cool down and then charge it. That's deep cycle. Hope that helps..

    Take it down to 4%, cool it down and charge back to 100%

    4-8% won't matter all that much, as long as it's 10% or lower...

    I have not noticed a difference with my 4 packs.
    Other than all being at 100% life.
