I recently acquired four NCR18650B cells, which are essentially standard 18mm-wide and 650mm-long cells with a built-in battery protection circuit to prevent overcharging and discharging. I obtained 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 protection adds 0.2mm to the width and 3.6mm to the length, resulting in an overall size of 18.2mm x 68.6mm. I also utilized inexpensive terminals for the end connectors: https://www.banggood.com/10-Pairs-Silver-Tone-Metal-Battery-Spring-Plate-Set-for-AA-AAA-Batteries-p-1046111.html To ensure they were securely fixed in place, I decided to bend the terminal by 90 degrees. The drawings for all assembled parts are included.
