Doing a shoot tday pop in my 47, says cell broken send in for repair, battery life is 92% with 40 charges, wtf!!! If i cycle the battery down will it mysticaly repair or am i screwed.
 
If it says cell broken I personally wouldn't want to mess with it. Lipos can hurt you. If you want to do ANYTHING with it I would recommend doing it outside or in a garage and stay a safe distance but keep an eye on it. I know it sounds paranoid but unless you want to dispose of it (there is a proper way to do that too) make sure you try to be safe around it. Make the call to DJI yet to see what they say?

Does it stay after a power cycle? I've had that message a few times as well but it was obviously erroneous as a power cycle would clear it, and watching individual cell voltages closely on the subsequent test flight close to ground showed nothing abnormal.

Additionally, when was the last time that pack had a full calibration discharge on it? If its been a while might be worth cycling down to cut off and then a full recharge.

The last time was the first battery firmware update, going to cycle it all the way down today.
