This is 18500 cells, i.e. 15 mm shorter than 18650 cells, this usual means a significant loss in capacity. With this battery the loss is not that bad.
The two cells tracks fine and has nearly constant capacity up to 3A load. This looks good.
Conclusion
This battery has good performance and good capacity, I will call it a very good battery.
