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 not have the same current limit, on trips at 6 ampere the other at 6.5 ampere.
The current limit is placed low enough to prevent overloading the cell, this is very good for people that want maximum battery lifetime without any risk of accidents, but not for people that want to play with high current direct drive configurations.
