This is one of LG's high current and high capacity cell.
This cell can be discharged down to 2.5 volt, because I stop at 2.8 volt I will not get the full capacity.











Fairly good tracking and good at handling high currents.















[size=+3]Conclusion[/size]

This battery is one of the very good high current and high capacity battery types.

Does the lower 2.5v min voltage gain an thing practical over a battery that is designed with a 2.8 minumum voltage? That is, does it possible indicate a more durable cathode design?

When using unprotected cells with leds it gives you a better safety margin. Even at low power it is difficult to over discharge a 2.5 volt battery in a light without a boost driver.

Thanks for your excellent review. HKJ! :thumbsup:
