This high current battery has a slightly uncommon size. The data above do not match the tested battery (Capacity is wrong).

Enercig%20EC-26500HP%202000mAh%20(Blue)-Capacity
The two batteries tracks fairly well in voltage while discharging, but there is some capacity difference.
The cells can handle 20A discharge current.

Enercig%20EC-26500HP%202000mAh%20(Blue)-Temp-20.0
The battery gets warm at 20A, but not too hot.

Conclusion
This battery is good at high current, but the difference in capacity means it cannot be used in series.
The marking on the battery and the datasheet do not match the capacity of the tested battery.
Notes and links
The batteries was supplied by ENERDan for review.
