Introduction: 18650 Battery Holder

You easely can make a 18650 battery holder from some PET bottles.

What you need:

- 18650 battery /from old laptop/

- 4 PET bottle

- hot glue gun

- scissors+ box cutter

- saw + abrasive paper

- some wire and battery contacts /from kid old game/

- soldering iron

Step 1: The Body

Cut the neck of the PET bottle. Make it with the abrasive paper or the box cutter. You need 4 neck for a battery. Cut a 4cm*8cm rectangle from the PET body. Make a cylinder from it. Pull on the necks to the cylinder and glue.

Step 2: The Tops

Make a hole on the battle tops. Put over the wire and soldering the battery contacts. Glue the contacts to the tops – just in case. Put on the battey and it is done. I use it for a headlamp,a flashlight and a bicycle lamp. If you use enough hot glue it is waterproof.

Great idea. Sure beats throwing them loose into a box like I usually. I am going to have to try this.
