    A high current cell in the new 20700 format.











    The discharge curves tracks fairly well and the cells can handle 30A nicely.





    But they do get warm at 30A















    Conclusion

    These cells are at the low end of capacity for 20700 cells, but instead they have a fairly good high current performance.



    Notes and links

    The batteries was supplied by Vapcell for review.

    Henrik, I think you meant
    Size: 20.5*70.2mm
    in the Official Spec.
    Thank you for another invaluable review.
    If you didn't exist we'd have to invent you.
