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 for your excellent review and dedication :)

Happy with the cells,i use some for ecig mods and also flashlight,so far holding up well. I am using around 9A of use sub ohm with 0.5ohm coils...........

Have just 6 at the moment as 3 are for my triple quad(based on supbeam x40)


Cant wait for the 3500mah 10a LG come spring/summer

Thanks for the test as always!

The 2v minimum discharge is nice for two cell MTG2 lights that don't have low voltage protection.
They won't barely even light up with only 4v so it's a good margin for error :)

Yellows can be found in SKIL cordless tool batteries. Have seen couple of them vented.

why does the HE4 even exist? the HE2 even has a lower internal resistance than the HE4

makes absolutely NO sense why they would release a worse battery!

someone makes sense of this!! :mecry::mecry::mecry:

Thanks a lot for your excellent review. HKJ! :thumbsup:
I have a question out of nowhere. The cell has N261I182A1 on its surface.
I think it means manufactured date. Do you know it? :confused:
