Newbie help!!!When reviewing my flight records in Phantomhelp, I am now showing cell deviations in my batteries. I always check the battery in the app before each flight, and everything always looks good, but when I download the record and view it, it shows (sometimes way out) cell deviations on all of my batteries (I have 3).
If I go and look at OLD flight records that initially showed 0 cell deviations, I am now showing deviations - am I doing something wrong???

I have seen at least two flightrecords here in the forum showing the same weird cell deviations. I have the impression that it is a malfunction in Phantomhelp. If DJI GO 4 shows you that all is well with the battery, you should be safe to fly I believe.

Thanks for the reply - that is what I was thinking, but wanted to make sure.

I would go by Go 4 myself - that will flag any abnormalities with the batteries and it seems all is fine.

may well be as wachtberger says - i hope so. you could also cross reference with airdata to see what they say your cell deviations are. you could also do a battery inspection. Check all surfaces to ensure there is no swelling (even the slightest amount) and keep an eye on your battery temperature.
Over heating could be an indication of something to watch out for.
If your app gives you a battery error notice then you should adhere to that warning and return for warentee replacement.

You can create a free account at AIRDATA to check your cell deviation too.

Hi, there, so sorry to hear the issue of the batteries, could you please provide a photo of the error message? We'll look into it, thanks!

I have checked mine on Airdata yesterday and it is a somewhat strange result too. Airdata says that all is well with my batteries but shows significant deviations too at the same time. I am wondering if this might be related to the fact that the MA has a new type of battery.

I will add this check function in my flight record analysis program, so we all can check it at home with our own flightrecord txt file
Next week i will publish the last version.

Interesting that airdata shows the same / similar discrepancy-
maybe then its the software update to the batteries has entered faulty information.
