Bottom Line: This is a 10A 2680mAh-rated battery that will often deliver 100mAh more at low current levels. Due to its very high internal resistance and lower capacity though it is easily outperformed by the Panasonic NCR18650GA, LG MJ1, and other high-capacity 10A batteries. I do not recommend using it over 18W/5A to minimize voltage sag.
The 18650 ratings table has been updated to include this cell.
