There is a significant capacity difference between the cells, this is not very good. The cells can deliver about 2A. this is fine for a 1.6A rated cell.

This is a huge difference in over current protection, one trips around 3.5A the other at 5A.

[size=+3]Conclusion[/size]

Both the cells has very good capacity and can deliver the rated current, but I do not like the difference between them.
