    Quality Batteries

    They work just as described. They also fit the heltec v3 which is what I used these for. The 2000Mah fits in many available 3D printed cases.


    They were perfection.

    1100 mAh batteries.

    All good. Fit the project I needed them for. Shipping was fast.
    I'll be back.

    Battery size

    The battery voltage and plug are as advertised, but the size which was a critical factor for me is totally incorrect. The dimensions for the 1100 mah battery as received were much larger than was shown in the product details, making them virtually useless to me. If you need size to be as stated, don't count on the published dimensions.

    We regret that the mm size was correct but the corresponding inch size was incorrect. We understand accurate measurements are important and thank you for bringing this to our attention. We have correct the measurements on the web page, so future buyers can rest assured it is now correct.

    It's a generic lithium cell. What is there to think?
