The discharge curves tracks very nicely and capacity drops only a little with increase current, at least up to the rated 20A.
But why do one cell terminate on temperature and other do not?

From this temperature chart the explanation is clear, I forgot to mount the temperature sensor on the A cell.
The battery gets rather warm at 15A

The cell without temperature sensor must have been very warm here. It was warm enough to get damaged!

The damage to the A cell is very obvious here.

And also on this curve. Due to this damage I had to cheat with the “internal resistance” value in the table, it is only for cell B, I did not use the value from the damaged cell.

Conclusion
The batteries has good performance but watch out for the temperature at high current.

Thank you again for the testing you provide.

I do hope the battery distributors would correctly label their batteries; this is not a true 20 amp battery. Until they do label them more truthfully your tests will remain very important.

These track really close to the EFEST IMR 3000 Purple 2016 discharge curves, but lag in total capacity a little.

Definitely not as good as the VTC6, but nothing else is.
