    Got lights! need batteries

    So I built a water resistant LED light because the technology available on the market couldn't keep up with what I could build one for. Now it looks like the cancer is spreading and I am finding the same is true of batteries . Does anone have any suggestions for building their own waterproof/resistant battery packs. I have looked at PVC and Vinyl tubing along with other options, but nothing has struck me yet as far as a good combination of weight and strength. I am sticking to AA or C NiHM individual cells right now because of cost and existing equipment. So I want something that I can slide cells in and out of and easily strap to the bike. I don't like the water bottle idea due to where my cage is located and want soemthing that I could change configurations easily when my lights/batteries change

    I saw this and may try to replicate it somewhat.

    Thought or what have you done.

    Cheers

    For waterproof, the water bottle is hard to beat because it's designed to be waterproof. You can pick up hardware that will let you mount a water bottle just about anywhere on the frame or handlebars.

    The only thing that really keeps me from the water bottle is having to solder - desolder to build it and I would have to buy an additional charger. Right now I am only set up to charge single cells. In the simple plan you are right, but who wants simple

    I store spare AA battery packs for my Dinotte in a "cage rocket"- holds 4 battery packs, 4 AAs each, easy in, easy out.

    Of course it's not waterproof. You could put AA packs in there in zip-locks, but who wants simple?

    As for the battery packs themselves, get holders at Radio Shack. They stock holders that Dinotte uses- 4 AA with a "9V" style snap top. They also carry the snaps.

    http://shop.willyselectronics.com/browse.cfm/4,114.htm

    The link isn't Radio Shack, but RS has the same thing for about the same price.

    When carrying more than one buy some spare snaps, cut off the wires, and cover the contacts. You don't want them bumping together and short circuiting. I stuck one in my pocket once, keys in the pocket. They touched the contacts and I ended up with a small fire and that's the bad kind of fire to have in your pants- destroyed the battery holder, the pocket, and roasted a nice little piece of my leg. I had another one melt in a different carrier, no fire, but it obviously shorted out (I still don't know what it shorted on, because there was no metal in it, but obviously something was conductive) and melted the carrier. Those little batteries are packing a wallop.

    Another option I sometimes use, a Fuelbelt frame mount bag. This one also holds 4 of the above battery packs-

    And they make a larger one-

    They also make red and pink, if you're into those kinds of things-

    I don't have them, so I don't know how many they hold. Naturally the frame bags aren't waterproof- zip-locks again.

    The Fuel Belt might be the thing to use. I am using 2 of the Radio Shack 8 AA holders in parallel right now so they should fit in there.

    Thanks

    I just 'eye balled' the small Fuelbelt. Check the length of your battery carriers. I'm not sure of the configuration of it, but if it's built the wrong way it might not fit the long dimension. Obviously it will hold 16 AA batteries since I get them in there, but maybe not in your configuration. I hope you've got a circuit breaker hooked up if you're running 16 NiMH AAs together like that. That's going to be 5 amp hours or higher at 9.6V. You'll get real fireworks with a short.
