Gravitrax Power Bank

thingiverse

Because I made a Marble lift with motor for my grandchild I had to make a powerbank for powering the motor of the lift. I also want the bank capable to control several things, I want to ad ESP32 processor, battery charger, some pushbuttons and rotary encoder. I still have to write the programs for the proc, but I already have some ideas. For the batteries I use 2 18650 types. The battery charger can adjust the output voltage and takes care of safe charging the batteries. The plugs for the power to the lift and other devices, still have to come from Ali, this takes still a few weeks. They are different as in the picture. If you can't find the esp and display look at Ali for Wemos esp32 and oled. In a few weeks I will publish a complete and working model. Send me a message if you like this project.
