Bike battery holder 3x18650 (12v - LED strip) - Parametric

thingiverse

This is a custom battery holder designed to fit three 18650 batteries in series, along with a built-in Battery Management Circuit (BCM) to safeguard the cells. It attaches snugly under the bike seat using two nylon cable ties and the tube of the bicycle frame for support. The top cap features an integrated switch that allows easy control over the system. I use this particular model to power a 12-volt LED light strip on my bike. Since I couldn't find a similar product or model available for purchase, I decided to create it myself. You can customize the design using the provided OpenScad file to fit your specific bike frame. Just remember to have fun with the process!
