Thread: Zebralight H600 Battery Extension

  1. #1

    Default Zebralight H600 Battery Extension

    Has anyone successfully modded a ZL H600 series headlamp with an external battery pack? I've done a search and seen lots of ideas/comments about it circulating but no actual confirmation/pictures.

    I'd be super interested in adding a second 18650 in parallel to the back of the head strap, to extend battery life and even out the weight distribution. Not sure if this would be viable though due to the limited clearances within the light with a battery inside. Still, where there's a will there's a way - anyone have an idea on this?

    It could be done if the battery is slightly loose in the light you could use a flat piece of copper insulated with tape on the side of a battery to the top and connect to the bottom of the battery and then drill a hole and run the wires out of it.

    Exactly what I was picturing in my mind. Possibly a lot more effort and design than what it's worth but it'd be a very interesting project. Has anyone successfully seen this done??

    Another option is to make a dummy battery and have wires out the bottom of it and a connector to it and then make a 2 cell pack with a connector wired to it to connect to the dummy battery/connector setup.

    I started doing exactly this a few years ago, then misplaced the glans connector and modified spare cap, never got back to it.

    Email zebralight for a spare tail cap, they'l explain how to order it - basically you have to order something from their online menu and then explain the substitution in the notes section of the order form.
    From there you drill the cap out to accept a watertight cable glans and make your dummy battery so that it can rest on the inside walls of the battery tube to prevent levering damage to the delicate cap.
    Cable goes to battery pack of cells in parallel.

    Eh4,

    Here's the thread where you originally introduced the idea and I built one. I use it all the time to this day. The build is post #90.
