High current AA sized LiIon batteries.










There is a small difference between the two cells and one of the cells has trouble with 10A, they both handle 7A

















Conclusion

The batteries are not perfect, but for high current 14500 they are in the top.



Notes and links

The batteries was supplied by ENERDan for review.

The wrapper was supposed to be blue, but due to a production mistake they got a gray wrapper.

Thanks HKJ.

It looks pretty good. However!,

The Windyfire seems slightly better until you get down to 3.4A where the Enercig sags less because of slightly more capacity.My batteries never get that low,I will stick w/ my Windyfire.

Upon further review,the Windyfire looks better at 5a and significantly better at 7a,at least for One of the batteries tested.

These and the TrustFire IMR14500 700mAh (red-gold) come from the same factory, I wager.

Maybe Enercig gets a “B” bin, and TurdFire gets a “C” (“A” is yet to be developed).

Cheers ^:)
