The two cells matches fairly well and can deliver some current, but at high current they get rather hot.

Conclusion
The batteries are good, but cannot deliver anywhere near the rated 50A, it is more like 10-15A continuous.
Notes and links
The batteries was supplied by Trustfire for review.
How is the test done and how to read the charts
How is a protected LiIon battery constructed
More about button top and flat top batteries

Thank you for the review.

So in the words of A. Lincoln:
You can Trust some of the Fire’s some of the time.
But you still cannot Trust all the Fire’s all the time.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

i think 50A is rated pulse current( or peak current) at very short time

i wonder what is under the wrapping?

Forgot my pen

More likely short circuit current, but I am NOT going to test that.

Taking into account the appearance of the positive poles (general appearance, number of legs, short overview of the CID/Venting System) and negative (grain of the metal surface, little information on this side, the withdrawal of one of the wraps of one of the tested cells would have affirmed or invalidated my assumption for sure because the Samsung have a punch, not the Sony) as well as the results obtained by HKJ (performance, temperatures, discharge capacities, etc.) all seem to indicate to me that These are Samsung model cell rewraps INR18650-30Q or 30QM (which is the same cell but manufactured in Malaysia).

Can a single flapping of a butterfly's wings trigger a tornado at the other end of the world?

In my opinion
Discharging and positive pole, looks like Sony VTC6
