This is the latest cells from Panasonic with the highest capacity.
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.

The two batteries does track nicely, due to the protection circuit the battery has slightly lower output voltage at high current.

Conclusion

This is a very good battery.
Like the EagleTac 3100 battery, this battery is very short for a protected battery, this can be useful sometimes.
