Eachine has a couple of batteries, this one is in the middle of the range.












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.
