Howto Video: Make a Coin Cell Battery Pack with Shrink Wrap

I really like coin cell batteries, specifically CR2032 models, but using them requires a small holder. This works well enough, but if you need to use several in series, things get out of hand size-wise. Here’s my solution: shrink wrap and hot glue to attach one or more coin cells together for an easy way to power your small device.

The concept is pretty self-explanatory, but check out the video below for a few tips on how to do this, as well as what I plan on using this with. You’ll need to use very large shrink wrap to fit over one or more of these batteries, and I used this package from Amazon. Between that and a few other heat shrink packs I’ve purchased, hopefully I won’t need any more for some time (but who knows).

For other coin cell ideas, check out my polycarbonate Christmas tree star, or my drink coaster made with four of these batteries. Also, you may notice that my video thumbnail style is a little different here. I’ve been experimenting with it, so I’d love to hear your feedback!
