The two cells are very well matched and as usual I test them a bit above specifications. They handled 20A fine, but did not like 30A continuous, it blew a fuse inside both cells, preventing me from doing the rest of the tests.

AT 20A they get rather hot, I measured about 78°C.

At 30A they reached 86°C before the fuse blew.

Conclusion
The performance of these cells looks very good and I will look on it as an advantage that they blew a fuse when overloaded (Instead of blowing up).
For vapers that want to use 30A, this fuse is no problem, I draw 30A for about 8 minutes continuous before it blew.
