The discharge curve is very good, it tracks nearly perfectly and the capacity do not drop much with loads up to 30A
Vapcell%20NCR20700%203200mAh%20(Gold)-Temp-15.0
A 30°C temperature raise at 15A, this is easy for the cell.

At 30A it gets fairly hot, but not too hot. 30A looks like a good rating for this cell.

Conclusion
This battery do not have more capacity than 18650, but it handles high current better that the best 18650.
I will call this a very good cell.
