Battery Deviations

I had a battery like that. DJI sent me a new one. Cell voltage deviation is too high and too many

How was the new one packaged when they sent it to you ??

I don't think you have any real concerns. The deviations are probably a product of your flight characteristics. The fact that you have major deviations is worth watching but as I understand the data that really isn't a big problem as you don't have more than 10... In a minutes time. I had a battery that I purchased that had 60 major deviations in one flight. Needless to say after learning of the issue in HD. I really babied the battery and it still had 30 major deviations... Well that battery was returned and not used again. So I would be aware of the battery temp and especially when it is cold really monitor the voltage. Additionally, I would not launch the bird a full throttle on a cold battery.

Cell voltage should be the same across the 4 cells or very close, always

I bought a new battery from Best Buy and only have 5 flights on it. I'm getting multiple "minor deviations" in cell #1. The battery has never been ran down under 50% and the deviations have appeared since the very first flight. Should I contact DJI and get a replacement?

No - having minor deviations is normal. All batteries have them.

Seems like there are too many in cell 1 though. Only 5 flights on the battery. My other battery's cell deviations never exceed 5 in a cell.

I emailed DJI last night and this was their response:

"Please try fully discharge the battery and then fully charge the battery, after that , please reply to this email with the following information, so we can better assist you.

Has the battery been involved in any rough landings or crashes?"
