This is a high current 26650 cell with moderate capacity.

The batteries easily handles up to 20A without any significant drop in capacity. The curves tracks fairly well, with only a minor capacity difference.
The 15A discharge curve for the A cell is missing, my equipment had a fault during the charging after the 10A test.

The battery gets hot during a 30A discharge, but not too hot.

[size=+3]Conclusion[/size]

A 30A discharge current is usual problematic for a 26650 cell, but not for here, the cell can handle it.
This is definitly a high current cell!

I emptied my battery and used my Xtar charger and it showed almost 4900mah in it when it was done it took around 12 hours to charge it. So from now on I use my flashlight to charge it. Big difference using 2 amp instead of .5 amp. Overall I am very happy with the quality of the battery.
