I need a simple yet sturdy battery storage box to hold my 18560 batteries. So, I designed a custom tray that can accommodate them.20 verses18650 batteries. The inner diameter of each battery compartment is19.0 millimeters——It is both sufficiently loose, making it easy to insert, and tightly fitted to ensure that the battery is firmly secured in the tray and not easily shaken. In addition, each battery compartment is slightly beveled, further enhancing the convenience of use.

Size：136×131×30

If you love this design, but its size doesn't meet your actual needs - either too large or too small - feel free to contact me at any time. I can customize trays of different specifications based on your specific needs, tailoring the most suitable solution for you.
