This is one of the high current, high capacity cells from LG.










There is very good tracking between the two cells. All the allowee currents (i.e. up to 20A) has only a small capacity drop, but 30A has both large capacity and voltage drop.
This cell can be discharged down to 2 volt, I do only test to 2.8 volt and will miss some capacity.















Conclusion

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