Introduction: 12 Volt VR Lead Acid Battery Holder

Have you ever wanted to use a 12 volt power source for a light or accessory on you bike, but found that your water bottle cage couldn't hold it? Well, here is a solution to a common problem us cyclists face. It's also weatherproof.

Step 1: Materials

You will need:

1 bar of aluminium, preferably 1" in width, the lenght will be adjusted to fit your bike
1 hex key or screwdriver, depending on what type of screw is used to fasten the cage to the bike frame.
1 drill bit of the diameter of the screw
1 drill or drill press
a couple of zip ties to hold down the battery(s)

Step 2: Drill the Holes

Match the drill bit to the diameter of the shaft of your screw, and then, sticking your pencil through the hole, mark where the holes in your water bottle cage where the screws go, and, using your drill press or your drill, drill the holes, and then move onto the next step.

Step 3: Bend the Aluminium

Now you are going to bend one end of aluminium at a 45 degree angle to make a secure end so that it won't slide down.

Step 4:

deattach water bottle cage and screw in the holder.

Step 5: Ziptie the Batteries

Fasten those zipties, and your ready to go! You now have a durable, aluminium battery holder that can hold batteries to power your lighting and accesories!
