There is good tracking between the two cells and they are protected, but the capacity is low and the over current protection kicks in at a fairly low current.

My 10 watt test failed, the battery could not maintain 10 watt due to the over current protection.

Over current protection kicked in, before I could do the chart.

Conclusion

This looks more like a 2600mAh cell than a 2800mAh cell, but with fairly low performance.
And the very restrictive over current protection makes the battery useles for high power lights.
The battery may be a good cheap battery, but nothing more.
