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.
