Make Your Own Li-Ion Battery Pack

In this project I will show you how to combine common 18650 Li-Ion batteries in order to create a battery pack that features a higher voltage, a bigger capacity and most importantly useful safety measures. These can prevent an overcharge, overdischarge and even a short circuit of the batteries. Let's get started!

The video gives you all the information you need to make your own Li-Ion battery pack. In the next steps though, I will present you additional, helpful information.

Here you can find a parts list with example sellers for your convenience.

Now that you have all the required components, it is time to do the wiring. You can use the pictures of my finished battery pack and the scheme from the video as a reference.

Here you can find the 123D file and the stl file of my design which you can use to 3D print your own enclosure.

You did it! You just made your own Li-Ion Battery Pack!
