Long story short, I was in need of a 3-5v battery pack that was lightweight, lasted a decent amount of time, and wasn't too big.
So I looked around for something, I had plenty of rechargeable batteries that suited my needs, but none that had dedicated chargers for them.
And then I came across my old cell phone. Unfortunately when I was removing the battery contacts I pulled a pad off the board. And there were no traces nearby to solder the wire to.
So, being the person I am, I grabbed another cell phone and made what you see here.
I made this battery pack and charger with intention of using it in my fursuit, but you can use it for pretty much anything you choose to.
Was it at all necessary to do all this work? Probably not, but I wanted it to look good since I'd be using it a fair bit.
Read on to see what I did.
Step 1: Tools and Materials
This stuff pretty much depends on how you want to do it, meaning you might not use the same tools (or materials) as me.
Some basic tools you will most likely need:
-00 or 000 Philips screwdriver (Or the appropriate screwdriver to disassemble your cell phone)
-Soldering iron and solder
-Scissors or wire cutters
-Marker or pen/pencil (I used a wet erase marker)
And any other tools that will make your build easier for you.
Some basic materials:
-Cell phone with its battery and charger
-Glue (I used hot melt glue and a glue gun)
-3 pin connector (Female, two of these)
-3 pin connector (Male)
-Enclosure of some sort (I used the enclosure from an old battery pack)
-N/O SPST switch (Just a regular pushbutton, optional)
And you can use whatever else you want to make the finished product look nicer.
Got everything? Let's build!
