And found this other pic. This seems to be a screenshot , and we can see that there is a window scroller on the right side of the pic, so probably more "cell" in other screens.

Didier, you’re Genius.
We will fid the single macrocell voltage, I am sure.
Here my values

It is strange that your PID 4885 shows only 10 values, I have 27

My PID : "62 00 62 00 63 00 63 00 62 00 62 00 62 00 62 00 62 00 62 00 62 00 62 00 62 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64 00 64"

Yes , already saw those pics.
Question is:
Which value JLR uses to define the battery SOH? They have (from bms) 6 values, 3 for power and 3 for capacity.
Furthermore they printed, in this report, not less than 36 modules, each one with a SOH value.
If Pathfinder extrapolate those value has to read, somewhere at least the single module tensions...

I suspect it was because my car was off when I scanned that value.

So if we take your PID 4880, and try to isolate value other than 00, this gives

Could this be a charging map on different condition ? high speed at the beginning , and reduced after
Just a thought !

Did anybody found the Pid for displayed Soc value? I mean the dashboard reported Soc thst goes from 0 to 100%. I know I can extrapolated that value from real Soc but I wonder if there is a dedicated Pid for that value. It would be useful while logging charging session as we all refer for comparison to displayed Soc and not to real Soc.

I don't, for the moment, but I am not sure it is available, or maybe in the Instrument Panel Cluster Module (720).
When I look at the OVMS code for other car, they usually try to "correct" the raw value with a formula.
