Bottom Line: This battery is often shown as a 6.4A 3400mAh battery but it’s not. The datasheet clearly shows its rating is 4.875A and 3200mAh. Due to its very high internal resistance and lower capacity it is easily outperformed by the Panasonic NCR18650GA, LG MJ1, and other high-capacity batteries. I do not recommend using it over 12W/3A to minimize voltage sag.
The 18650 ratings table has been updated to include this cell.
