This cell is slight thicker (2mm) than 18650 cells, with about the same capacity. This means it must be a high current cell.
I had a glitch on my test station and the 0.5A value is only for one cell, not average for both.

The capacity is a it on the low side for a 3000mAh cell and the two cells do not track, but the high current handling is in top, it do the 30A discharge without much capacity loss.
