  • Storage Temperature: 1 month -20 ~ 60°C, 3 month -20 ~ 45°C, 1 year -20 ~ 20°C




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.

Eagerly awaiting this test , but it has more voltage sag than the HE2(KP IMR 2500),Sony VTC5 and 25R(Basen 2500) at all currents.

I’m not really sure why they released this cell , I will not be replacing HE2s with HE4s at this rate.

Thanks for the testing , definitely useful.

I’m very interested in HKJ’s opinion on this subject

In my own tests , I myself saw the same results with the HKJ.
Somewhere I had read however, that HE4 resist higher temperatures .
If this is improvement in relation to the HE2 , personally do not excite .

Thanks HKJ.

i have a question, i bought lg he4 from gearbest but it doesnt have the “134” printed. it is fake?
