I designed my own version of a 4-battery power bank using 18650 cells. To build this project, I needed the following components: * Dual USB 5V 1A/2.1A Mobile Power Bank 18650 Battery Charger PCB Module Board * 4 x 18650 NCR18650PF Panasonic 2.9Ah Li-Ion Batteries I chose not to solder the batteries in place, so I can easily swap them out if needed. To assemble the power bank, you'll require 4 M2x18mm screws with construction nuts and some battery connectors.
