    I had an issue with one of my batteries swelling up. Would go into low battery mode and start loosing power around 55%. Sent that back to get replaced and now i am looking at my other battery and cant really tell if it is swollen or not. It has a little squish to it but not nearly as bad as my other one, plus i dont have any early low battery warnings with this one. My question is if i plus the quad into the computer and im looking at the battery section is there anything that would be a give away of a failing battery?

    I also noticed sometimes controls are a bit delayed, i thought maybe it was due to the bad battery but today when I was flying it seemed like getting it to come back to me was a little hesitant and then there were times it would shoot forward. It was a bit windy so im not sure if it was just wind gusts holding it back or if this could be another issue?

    The cell voltage from each cell on my bad battery were pretty similar. Took a picture before i sent it back here was the readings:

    Cell #1: 3789
    Cell #2: 3782
    Cell #3: 3775

    Voltage was at 11346 mV and Current was at -1504mA

    Any of this sound strange?

    A swollen battery won't always have a large difference in voltage/current, in the early stages.

    Anyone know if the delayed controls would be a battery issue or not?
