The cells can deliver 20A with full capacity and the maximum difference in capacity is about 0.6%.
The voltage at the lower currents is not very impressive, but in the 10A to 20A range it can match IMR cells, but with greater capacity.

Conclusion

This is a very good battery, but there is no reason to use it, except if you need a lot of current.
The R version of the battery is slightly better.
