The battery handles anything up to 10A without problems, it might also work at higher current, but I have not tested it.

Conclusion
These IMR batteries have good performance at any load, but the capacity is, of course, not that high.
At the current time I can only rate them acceptable, because Efest is a new company, and the batteries is not from one of the big brands.
