I am using the LilyGo T-Display S3 Pro for this nice-looking battery charger project. Lithium batteries are connected to one of the header pins or connectors. On the display, you can see the voltage, current, and other data. I can set target voltage and charging current. Sponsor of the video is PCBWay
pcbway.com . Thank you PCBWay for help!.
