Very nice discharge curves with a good match and capacity drops slowly with higher current.

I forget to put the temperature sensor on the A battery

By accident I started a "small battery test" instead of a normal test for the A cell. This means it will include a 100mA discharge, charging current is 0.5A and this test here only goes to 7A

See text above.



Conclusion

This is a very good high current cell.
