This battery performs like the Panasonic 3400mAh cell with added protection.

The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.

After shipping the samples to me, some print was added to the box.

The discharge curves has good tracking, but the protection in this battery has a rather low current limit, it prevented doing a 3A discharge test.
