Electric bicycles use batteries made from lithium ion cells. One of the most common types is a cylindrical cell called an 18650 cell, named so because it is 18 mm in diameter and 65 mm long. I'll show you how you can create your own DIY electric bicycle battery from these cells for much less than the cost of a retail ebike battery.
It's actually quite easy, and because the prices for these cells get even better when you buy more of them, I often buy an extra large pile of cells and just make extra batteries to sell locally. That way the batteries I make for myself end up being free!
To make your own electric bicycle lithium battery you'll need the following, and more details about each are included below:
Battery management system (BMS)
Soldering iron and solder
Heat shrink tube
Miscellaneous wires and connectors
That's everything! I test fit the battery and it slid in the bag nice and snug. The little door at the back covers the connectors and allows me to access them without removing the battery each time.
I hope you found this helpful and feel free to ask any questions in the comments below!
If you'd like an even more detailed writeup, I created a how-to article here, and I also made a video on youtube that shows this whole process on a different shaped battery here.
