The New Hotness

  • Monthly Science: Batmax NP-BX1 Status

    After powering my Sony HDR-AS30V helmet camera for nearly all of this year’s riding, the Batmax NP-BX1 lithium batteries still have roughly 90% of their original capacity:

    Batmax NP-BX1 - 2020-11
    Batmax NP-BX1 – 2020-11

    Those are hot off the Official Batmax charger, which appears identical to other randomly named chargers available on Amazon.

    They’re holding up much better after a riding season than the DOT-01 batteries I used two years ago:

    Sony DOT-01 NP-BX1 - 2019-10-29
    Sony DOT-01 NP-BX1 – 2019-10-29

    Empirically, they power the camera for about 75 minutes, barely enough for our typical rides. I should top off the battery sitting in the camera unused for a few days, although that hasn’t happened yet.

    Of course, the Batmax NP-BX1 batteries I might order early next year for the new riding season have little relation to the ones you see here.
