    Default Test/Review of LG 18650 HE2 2500mAh (Red)

    LG 18650 HE2 2500mAh (Red)



    Official specifications:
    • Nominal Capacity: 2,500 mAh
    • Minimum Capacity: 2,475 mAh (Cmin)
    • Nominal Voltage: 3.6V
    • Standard Charge: Constant current 1250mA, Constant voltage 4.2V, End condition(Cut off) 50mA
    • Fast charge: Constant current 4000mA, Constant voltage 4.2V, End condition(Cut off) 100mA
    • Max. Charge Voltage - 4.2V
    • Max. Charge Current - 4000mA
    • Standard Discharge: Constant current 500mA, End voltage(Cut off) 2.0V
    • Fast Discharge: Constant current 10000mA, 20000mA, End voltage(Cut off) 2.0V
    • Max. Discharge Current For continuous discharge 20000mA
    • Weight Max. 48.0 g
    • Operating Temperature (Cell Surface Temperature) Charge 0 ~ 50C Discharge -20 ~ 75C
    • Storage Temperature (40% charged): 1 month -20 ~ 60C, 3 month -20 ~ 45C, 1 year -20 ~ 20C
    • Cycle life to 60% capacity: 300 cycles(10A) or 200 cycles(15A)




    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.

    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

    Interesting to see, in HKJ's comparator, that the older HE2 outperforms the newer HE4.

    The HE4 test:

    Hi there,sure yellow are 20A and these red 25A rated,so presume priced accordingly. Not seen the yellow available as much,reds i have seem more available...........if makes sense.

    edit-looked mine up and shows 25a and 35a short burst.

    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!!

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

    I do not know it, but it might include a date code.
