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.















Conclusion

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