A regular 18650 battery, this battery is neither high current or capacity. It is fine for many flashlights, but not for high power vaping.

This battery has a flat top, but has some bumps on the bottom, to secure connection when used in series.

The two cells has good tracking and fairly stable capacity. At 7A the capacity is starting to drop, but it is above rated current.

This is about rated current, the battery get a bit warm.

At 7A the battery get hot.


The battery looks good and is fairly good at maintaining voltage during discharge.
