Official specifications: AW%2018500%201500mAh%20(Black)%202016-info

This cell from AW is a bit shorter than 18650 cells and is used in a few devices (2 of these cells matches 3 CR123 in length and voltage).

The discharge curves looks good, the two cells match nicely and capacity is nearly constant independent on load, but the cells are not for high current.

Even when discharging at 5A, the cells do not get unresonable hot.

Conclusion

I have a suspicion that just about all 18500 cells on the market uses a old design and that is the reason for the fairly low capacity.
With that said these cells look good up to a few amps.
