The batteries easily handles up to 20A without any significant drop in capacity. The curves tracks fairly well, with only a minor capacity difference.
The 15A discharge curve for the A cell is missing, my equipment had a fault during the charging after the 10A test.

The battery gets hot during a 30A discharge, but not too hot.

Conclusion

A 30A discharge current is usual problematic for a 26650 cell, but not for here, the cell can handle it.
This is definitly a high current cell!

Good looking solution for high current needs, around 7amps or more. Otherwise Shockli 5500mAh 26650’s for long run time.
Thank HKJ.
