Hello Everyone!

I was working on a Project, in which I am almost done with, but I needed an Inline Power Pack. I looked around and I couldn't even locate one! The reason why I needed an Inline Power Pack was due to the internal specifications of the project that I was working on. I thought that I would just build one and in turn I came up with a way that everyone could build one and easily and inexpensively make it to have the voltage specifications of your project needs.

Well Guys and Girls, I hope you like this idea and can incorporate it into your project if you have a need for it too!

Step 1: Determine the Battery's Dimensions

  1. Before measuring the battery, be sure to apply electrical tape over the battery ends (+ & -) so you don't damage your battery or cause any unwanted actions to occur.
  2. Measure the length and width of the battery.

Step 2: Step 2: Select a Cylindrical (non-metallic) Tube That You Battery's Fit In.

I have a section of PVC Pipe left over from a old project which will work out just fine.

The inside dimensions of the PVC Pipe is 1 inch, which will work perfectly!

The C-Battery Length was 1.95 inches, so if I wanted to stack up (3) C-Batteries, we would multiply the length X 3. Which, when we add the batteries in Series would give me 4.5 Volts.

1.95 X 3 = 5.85 inches

Now, we need to add a little bit of room in the end caps for the Battery Terminals, 3 millimeters or 1/8" will do.

Step 3: Step 3: Cap the PVC and Add Terminals

During this step I needed to put a cap on one end of the PVC as well as put a spring in the bottom of it.

  1. I took the spring out of the Broken VCR Remote and bent the base wire outwards.
  2. Next, I took a box cutter and cut a small divot out of the edge of the PVC so the spring terminal could extend outwards.
  3. Then I cut (2) circles out of the VCR Case to make end caps for the PVC pipe.
  4. On the bottom end where the spring was going to be located I glued the spring and end cap into place.
  5. I drilled matching holes in the PVC for the positive end cap so I could easily remove it when I needed to replace the batteries.
  6. For the top end cap I cut a strip of the VCR Metal Sheeting that was located in the top of the VCR for the positive terminal. I bent the sheeting strip over my screw driver to achieve a slight curve.
  7. After scratching the cap and metal strip (to give a better adhesion) I glued it into place.

Step 4: Step 4: Test It!!

Connect it, Test it..... It's Alive!

I've procrastinated publishing for ages. </p><p> I'm not sure if mine will work well with normal cells. The strips that hold my re purposed cells together kinda act as springs. Maybe if one had your spring at 1 end, and my nail at the other, it would be the best of both worlds. You've gotta cut yers open to replace cells having glued the ends. Mine is a simpler build, and easier to take back apart.</p>
<p>The negative (bottom end) of mine is glued. The Positive (top end) has 2 small screws holding it together. Maybe I forgot to post that part... I'll go back and check tonight.. Thanks for the comment.</p>
a bit ambiguous directions re: gluing 1end and screwing the other. also, what glue didja use?
<p>I went back and looked. </p><p>It's located under Step 3: </p><p>No. 5. I drilled matching holes in the PVC for the positive end cap so I could easily remove it when I needed to replace the batteries.</p><p>The glue that I used was Loctite Super Glue Ultra Gel Control</p>
Very clever and very simple.<br><br>You don't even need a 3D printer!!! That's a bonus.<br><br>sorry for the outburst. <br><br>ahem... as I was going to say.....<br><br> I've been trying to workout how to make a splash proof case for my niMh and Ni-CAD battery packs and still stay compact and portable.<br><br>With your idea and some Sealant you've solved my problem.<br><br>Thank you.
<p>That's Terrific!</p><p>During my search I found different size PVC Pipe fittings that were threaded too. You could always seal the threads with teflon tape, so you can take it off easily. </p><p>I'm happy that I could help you while doing my project!</p><p>I'm really starting to enjoy this Instructables website!</p><p>Thanks again for the positive comments and good luck! </p>
