This is a high current 18650 cell with moderate capacity.











The discharge curves has nice tracking and nearly constant capacity up to 20A.





The battery warms up during a 20A discharge, but not too much.



30A discharge is not really for continuous discharge.















[size=+3]Conclusion[/size]

This is a very good high current cell.

He did send one more to test. We are at the time of year where my review queue is growing, i.e. it takes a long time to get anything reviewed.

I can imagine HKJ, we all sure appreciate your time/effort in your very useful reviews.
