The battery works fine up to 2A, but is not that impressive with a 3A load.

In this test I do overload the battery and one of the cells looks like it is running out of power.
When calculating the internal resistance I used the voltage drop between 2A and 4A.

Conclusion

I am not that impressed with the high current capabilites of this cell, but because it is better than most ICR batteries, in the same size, I will rate it as a good cell.
