Mini2 battery cell imbalance

[Deleted member 154384]

I recently purchased a mini 2 combo and after the first three flights, I noticed that one battery, compared to the other two, has a slight imbalance of the two cells.
Do you think this is normal or should I worry? Another problem is that if I plug the battery into an instrument called Battery Power Discharger, this battery always reports "0" cycles while the other two give "1" cycles.

I'm no expert but I would say that the difference would be well within the expected variations.

The graph says that 0,025v is minor/normal so no probs.

...a slight imbalance of the two cells.
Do you think this is normal or should I worry?...

If you click on the Battery Cells tab, Airdata have summarized what's a minor & a major deviation ... 0,025V is classified as a minor deviation & is perfectly normal... even hitting a major deviation (above 0,07V) occasionally (1-4 times) during a single flight can be considered as normal, especially if the flight circumstances isn't favorable for a LiPo battery, like really hot/cold ambient combined with high amp draw as during Sport mode use with full left/right stick command.

Thanks for the reply guys! it was just to figure out if there was a problem with the battery or not. I find Airdata really very complete and interesting and I didn't think you could have so much information about the drone!
