Hi All,

I bought one battery last week (3 cycles) and i can see in the cell #4 a lower voltage than others, usually 0.03 - 0.04V.

In the airdata.com, Battery cells shows:

Do I need to worry?

Please keep an eye on your batteries. You want to update the firmware for the batteries as needed. Remember the warranty aspect of the battery: http://www.dji.com/service/policy

Do you have a screen shot of the Go 4 App? I would put more reliance on the Go 4 App.

I have the same problem with cell 4 on a high capacity battery and cell 3 on a standard capacity battery so far I've just been keeping an eye on them, I have not seen any issues yet. However, I really would like to know if someone out there has experience with this situation or other insight on the subject.

Hi Mark,

In DJI GO 4, everything is ok, no notifications about battery. I only see the difference of voltage between cell 4 and others.

Keep in mind these batts only have a 6 month warranty...first sign of a true issue or app warning I'd send it back.

My 3 week new battery in my new P4 looks the same. And it's really frustrating there is no port to hook up a real battery balancer.

i agree you, its really frustrating..
Now I fly with concern!

I think you have reason to be concerned, but I also can say that your batteries will not always be exactly the same. I guess I am referring to your cells. Minor deviations are to be expected I think. My batteries seem to bounce around a bit too, but your app and/or your aircraft will tell you if you get a cell out of whack. Keep an eye on things, and if you continue to see deviations, you might be able to get the store/DJI to replace it.
