A high current rated 26650, it lives up to the capacity rating, but the current rating is way to high.

Up to 10A the curves looks good, at 15A one of the cells has a problem and at higher current both cells has problems.

Conclusion

The cells performance is fairly average for 4200mAh 26650 cells and is not really useable for 30A or 60A current, but works fine up to 10A.

So, another outfit sticking on their logo wrappers, on unknown cells? It seems like it is a trendy think with cells lately.

Thanks for the review. I don't buy any chargers or cells until they have been reviewed by you.

It has been a trend for years, the first one was AW I believe, but the LiIon market has increased significantly, especially due to ecig users. Many new companies has seen a business in this.

I would have been nice if more of them got a good electronic load and did some quality control on their cells.
