    Default Test/review of Shockli 21700 4550mAh (Purple) 2018

    Shockli 21700 4550mAh (Purple) 2018



    Official specifications:
    • Nominal voltage: 3.7V
    • Nomimal capacity: 4550mAh
    • Maximum continuous current: 22A




    High capacity and high current in the new 21700 format from Shockli.











    The two batteries are matching very fine and can handle up to 20A. They cannot deliver full capacity to 2.8V, but maybe to a lower voltage.





    The batteries gets fairly warm at 20A



    And I had to stop at 30A















    Conclusion

    The batteries has lot of capacity and can deliver fairly high current, it looks like good batteries.



    Notes and links

    The battery was supplied by shockli.com for review.
