This is fairly high current batteries with acceptable capacity.

There is a small capacity difference between the two batteries, they do not like very high current discharge (30A)

Something went wrong with the A cell for this test, it was fully charged, but the discharge was skipped.

I wonder about the temperature difference, maybe I forgot to place the sensor on the B cell, but it must have been close.

Conclusion

The batteries handles 15A fine, but 20A is at the limit. Performance is as expected from a high current battery.
