This is a 18500, these batteries usual has fairly low capacity and this battery is no exception, but it can deliver a lot of current.

There is good tracking between the two cells and the capacity is nearly constant independent of load, even at 20A

[size=+3]Conclusion[/size]

These battery has very good high current performance, but the size limits the capacity (If you have 15mm more length, you can get more than twice the capacity).
With the performance of these cells, I will call it a acceptable battery.
