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.











These batteries are good at both low and higher current.















Conclusion

This battery has higher capacity and better high current capacity than its predecessor (3100mAh/NCR18650A).
EnerPower has added a good protection to a good cell, making a very good battery.
