A high capacity and high current 26650 cell from AWT. The current speifications from AWT's website do not look anywhere near correct.











The two cells are the same at handling loads, but there is a capacity difference, i.e. do not use them in series. They are also significantly below rated capacity.















Conclusion

Significant difference between the cells and both below rated capacity, not the cells I would go for.

thanks, for your continual hard work.
Your tests are invaluable to us!

I have never bought AWT cells, and it looks like I’m not going to in the nearest future neither!
Thanks for your awesome tests!

I just don’t get why they even send you these batteries for review (unsolicited, I suppose). They should be aware that your test will debunk their performance claims and ruin their name.

5

I do also wonder. I would expect they assume their cells to be good and that would maybe mean that their supplier has cheated them with a bad batch.

6

If so, then they are not doing any tests on these batteries themselves. Otherwise why would they come up with these ridiculous claims…?
It looks like they are just rewrapping these cells…

7

At least not on each batch.
