How To Make A Lithium Battery Pack With 18650 Cells | Practical Skills For Makers

In this video I show you how to make your own custom lithium battery pack using the common 18650 lithium cell. I talk about how to connect the cells in series to get the desired voltage you need, and how to connect the cells in parallel to increase the capacity of the battery pack. Then I go over how to arrange them in the plastic spacers, and how to use nickel strip to spot weld the cells together. Finally I talk about using a battery management system (BMS) to add protection and properly balance the cells as you charge them. I wrap the whole battery in a protective insulating layer and shrink wrap.

New videos are uploaded on Fridays!

If you're like me you have creative ideas that are trapped inside your mind. Byte Sized Engineering videos will give you the knowledge, inspiration, and confidence to make your creative ideas a reality. You are more capable than you think, and I want to help you unleash your inner maker!

You shouldn’t need an engineering degree to make your ideas a reality. I suffered through years of engineering school so you don’t have to. I know how it feels to want to make something I’m excited and passionate about, but also feel overwhelmed by not knowing where to start. I’ve unlocked the secret to getting past this feeling of being stuck. In my videos I show you how to take complex problems and break them down into smaller, more manageable “byte sized” pieces.
