Battery Holder for a protected 18650 Cell

myminifactory

I recently purchased four protected NCR18650B batteries, which resemble standard cells with an 18mm width and a 650mm length. However, these batteries come equipped with a built-in protection circuit that prevents overcharging and overdischarging. I acquired them from https://it.aliexpress.com/item/new-4-pcs-original-protected-18650-rechargeable-battery-3-7-V-3400-mAh-battery-for/32654934119.html. The inclusion of this protective feature adds 0.2mm to the width and 3.6mm to the length, resulting in an overall size of 18.2mm x 68.6mm. To connect the battery terminals, I used inexpensive connectors available at https://www.banggood.com/10-Pairs-Silver-Tone-Metal-Battery-Spring-Plate-Set-for-AA-AAA-Batteries-p-1046111.html. For added stability, I decided to bend the terminal by 90 degrees, ensuring that it was securely fixed in place. The drawings for all assembled components are included.
