This is a 17500 cell, i.e. it is both thinner and shorter than a 18650 cell

I did test this battery with a much higher current than it is rated for. Below or at rated current it does very good, it does also work very fine at 2A and 3A current (But expect shorter lifetime).


The battery does easily handle the speficed current and more, i.e. performance is good.
A usual this type of battery gets an acceptable rating.
