The two cells match nicely and handle current up to about 10A where the protection kicks in.

The battery may deliver 15A peak current, but as usual with protection the trip limit varies with time the current is on.

[size=+3]Conclusion[/size]

It is a good battery, but with the protection the maximum continuous current is about 10A. The protection do also provide over discharge and charge protection (They always do).
