One of the cell has the rated capacity, the other have less capacity and neither of them can deliver more than 1A to 2A. This do not look like a high current cell.

Conclusion
This battery is not a high current battery and the mismatch between the two cells is rather high.
It looks like it has a working overload protection, but at a way to high value.
