I have created a table to understand the percentage readings of the China monitors.
It is (still) completely fuzzy, because I don't have enough values. But you can already see how much the percentages depend on interpretation. I have taken the volt/DoD figures from the pictures posted here. The columns name the respective sources.
The "INEOS" column is the most complete. I used only the "discharge" values, since the "charge" situations seem to show only what the generator delivers, but not the actual battery voltage. This becomes obvious if you see that the voltage values for charging and discharging are completely different at the same DoD percentage.
But also the discharge values are to be taken with caution, because discharging with 8 amps or with 16 amps results in different voltages (although I consider the difference for such large batteries negligible within this current range).
But as an approximation, it is already clear that the INEOS curve is not linear and, to my understanding, seems to be defined with some thought behind it.
I personally trust the INEOS values the most.
If we collect some more readings here I will add them to the diagram.
For the INEOS readings, only report 'discharge' readings with no more than around 15 Amps.
