A very high current 18500 cell.










The cells are good at high current, but the capacity is not matched.





The temperature raises fast at 20A, but stays at a safe value.















Conclusion

These cells are good at high current, but due to the capacity difference they are best not to use in series.
As is usual the case with high current cells, the capacity is not in top.

The batteries was supplied by ENERDan for review.

Thanks HKJ. :+1:

Thanks for the test! The current capability is great but the capacity is indeed a bit low for the cell size. I hope for medium to high current 2000+ 18500 cells sometime in the future, for my collection of 18500 flashlights.

*(If not wrong, should be the same battery with the known blue Tensai)
*
If those are the same batteries to Tensai, then talk about the 18500 best batteries that I’ve worked.
I have AW 18490, the 18500 Keeppower and Tensai 18500.
Among these batteries, I saw the better functioning of the Tensai.
Best mode to issue power.
In duration and durability, I did not see a difference.
It is by far higher than the Panasonic / Sanyo 1700/2000 in force.
With higher discharges of 3 + Amperes, is clearly superior.

So if the batteries of Enercig identical batteries of Tensai, then talk about the superior battery of this size.

Compared with several other such size ……, there is simply no comparison.

I refer of course to discharges of more than 3 - 5 + Amperes.

It might be, the same company also sells Tensai

Exactly.
That is why I believe that it is the same battery.
Thank you once again for your trouble bro.
You have helped many people ……

My compliments HKJ….
