[size=+3]Conclusion[/size]

I have tested a 5200mAh from Keeppower before with about the same result. The capacity is very good for a 26650 cell and it can deliver some current.

Thank you again for the time you spend for these reports.

I have four of these batteries and have been pleased with them.

Identical in performance to the ones you tested in 2014. Must be the same cell, just with a new wrap and label.
