Fairly high capacity, good current and not that expensive, is this cell as good as it looks?
Discharge curve looks good, the tracks fairly well and capacity is nearly constant up to 15A.
At 30A the cell get hot enough that I terminates the test a bit early.
Conclusion
The cell live up to its rating and is one of the top performers for 26650 at the current time.
