(Searched and saw some info on Major Deviations, but not much about minor ones.)

I uploaded all my logs to HealthyDrones and noticed that both of my batteries show a lot of "Minor Deviations" in Cell #1.

I have two batteries. The one that came with my Phantom 3 Std showed 53.8 minor deviatons right out of the box. (Cells 2-4 showed 0). It only has 4 charge cycles on it, and over this time it has varied from 41.6 to 55.6 in cell#1. Cells #2-4 occasionally have minor deviations of 1 or less.

Battery nuber two only has 2 charge cycles on it. It started out with 12.5 minor deviations in cell #1, with deviations less than 1 in the other cells. The three flights I've done on this battery show minor deviations of 12.5, 11.5, and 11.1, with deviations of 1 or less in the other three cells.

Healthy Drones says minor deviations are normal, but I wonder why they all occur in cell #1 on both batteries, and why did the battery that came with the drone start out with cell #1 minor deviations of 53.8, which is into the "Yellow Zone" on Healthy Drones?

Here's a screen shot of the battery info from my latest flight today:

Should I contact DJI about this battery?

Thanks,

By the way, neither battery show any Major Deviations so far.

Minor deviation are just that, minor. No need to be concerned. Even major ones are normal now and than, I have a few on both batteries of mine, and use them on every flight, no problem.

If the drone is flying great for you, then you have no concern.

But keep an eye on them, as you are already.

I get almost the exact same display from HealthyDrones on my new (just received) battery, and something else on the original battery which has a lot more flights.  I just take them at their word when they say the battery is fine... too much information that I don't understand the implications of isn't helpful anyway.

The batteries work fine.  I agree with the others, don't worry about it.

OK, thanks for the responses. I'll stop worrying about it unless things change.
