4S1P 18650 Battery Case

thingiverse

This case is designed specifically for a 4 x 18650 cell battery, which I'm using in this prototype. The eBay item number for the battery I've chosen is 161975785075, and it comes equipped with built-in protection features. A standard rocker switch can be inserted into a dedicated slot on the case, while a DC jack is also included for easy connection to other components. Additionally, there's a hole designed for a standard chassis mount fuse holder. When working with Lithium cells like these, it's essential to remember that they pack a lethal punch if not handled correctly. If you're unsure about what you're doing, please don't attempt this project on your own. As I'm still new to Tinkercad design, excuse the rough-around-the-edges approach to this prototype. One key tip for getting the best results is to adjust the infill setting to a high level for added strength. Additionally, consider using support for the switch hole to ensure a secure and stable fit.
