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.

Thanks!

Nice review, these batteries are excellent in my mods manage to get more current than 20r or 25r Smile

Sorry for my bad English…
