    Default Test/review of Vbatty IMR18650 3000mAh V30 (Blue-gold)

    Vbatty IMR18650 3000mAh V30 (Blue-gold)



    Official specifications:
    • Brand: Vbatty
    • Size: 18650
    • Chemistry: IMR
    • Nominal Capacity: 3000mAh
    • Nominal Voltage: 3.7V
    • Discharge: 30A Continuous, Rated 40A Max Pulse by Vbatty
    • Positive: Flat
    • Rechargeable: Yes
    • Dimensions: 18.23mm x 65.02mm
    • Weight: 46g




    This is a high capacity and high current battery.











    The discharge curves has good tracking and capacity only drops slowly with load. The battery has trouble at 30A due to heat.



    The battery will get warm at high current.



    At 20A it was very close to a termination due to temperature.



    At 30A I had to stop due to temperature. The battery reached 86°C after I terminated.















    Conclusion

    This battery has very good performance for both capacity and current.



    Notes and links

    The batteries was supplied by Shenzhen Vbatty for review.

    How is the test done and how to read the charts

    Thanks for the review!

    I will have to compare these to the top IMR batteries!,,,,,Using your comparator of course.

    EDIT: I am impressed.In terms of Voltage sag,,,,,,,,,, It is slightly better than LG HG2, Basically even w/ the 30Q and ONLY bettered slightly by the VTC6!

    I am taking a wild guess and saying that it is using a 30Q cell. Throughout different voltages the curves are basically identical.
