    Quick release connectors for helmet lights?

    Hi there - I'm looking at making a helmet light. I want to put my battery pack on my rack as it's gonna be pretty hefty (250WH of lipoly goodness). So that means I'll be running a cable from my bike to my helmet. I seem to have a tendency to get launched from my bike... Last time it was an ice slick that sent me sliding for about 30 feet... so I have this fear of getting launched from my bike and then getting yanked back by the cord going from the battery to my helmet. So I'm thinking I need to find some sort of quick release connector. Some Apple laptops have really nice magnetic quick release connectors - so if I could find a waterproof, 4 pin version of that I'd be really happy. (4 pins as I want to run control signals on this cable, as well as power)

    Any suggestions?

    Velcro works well if you are using a flat bottom housing.
    Holds tight. Doesn't bounce. Release depends on how much you use.

    Oh - I was thinking about an electrical connector... So you're suggesting have the light itself detach when you get thrown? That scares me a little... seems like it could get totally wrecked...

    OK. Thought you were talking about a mount. Easy release power connector. Not sure on any of those. Rigors of biking could play havoc with keeping a good connection.
    Best of luck with the project.

    I'm most concerned about low hanging branches. The velcro should work for that. Most any press together connector shoudl be OK. Twistlock or other style positive locking connectors might not be such a good idea.

    Get a smaller battery that you can put in your pack. Heck, get two or three and put the extras on your rack. Loose cables hanging from your head are a recipe for a hangin.

    I think these are 1/4 turn locking DC power connectors.
