Laptop Powerwall 107 - 24-cell 18650 charger with voltmeter

I've just finished building a new 24-cell 18650 charger - this time with a voltmeter so I can quickly check if a cell is already fully charged.

Voltmeter I used: https://www.aliexpress.com/item/0-28-inch-LED-0V-30V-DC-Three-Line-Digital-Voltmeter-Home-Use-Voltage-Display-Blue/32791013374.html

TP-4056 Modules I used: https://www.aliexpress.com/item/10-pcs-Mini-USB-TP4056-1A-Mini-Lithium-Battery-Charging-Board-Charger-Module/32343019512.html

This will be used by the Lucid Dream Bikes community arts project to charge cells for their small battery packs: https://www.youtube.com/watch?v=jA0EhvJgagM
