I have two batteries showing this. Should I be concerned or wait 'til they get much worse?

ld check the cells voltage in the app when the battery is full charge. The above is not always reliable, I had new batteries show me similar after a long flight.

Thanks, Suren. I flew this same battery a few minutes later for a short flight with almost 0 variation.

This was caused by just one battery cell going bad last year. It flew an entire flight fine and dropped from the sky while doing it's return to home. Your's may be a fluke warning but this is a reminder what is always possible.

If this is your only battery doing this, i would replace it.  You don't need the aggravation of a mishap.

Airdata can be unnecessarily alarming.
The number of variations isn't what matters.
It's the size of the variations.
You'd need to look at the cell voltages through the flight to tell if it means something or if it's nothing at all.

Here, Labs, what do you think?

I would upload that flight to Phantom helper, it also gives battery voltages per cell.

Airdata says no major concern, see image from you flight below.

Airdata isn't showing your actual data to be able to see how large or small these deviations are.
It's probably nothing to worry about, but I'd want to see the numbers to tell.

Phantomhelp is what's needed.

I just discovered something useful you may be able to use in future.  Go to the "Cells Graph" tab. Put your cursor over the Cell Deviation graph and it does show each cell voltage along with deviation. You can also expand the graph for a closer view. It is less than .02 over the duration of the graph. From .012-.018.
