Thanks Peter

Im a complete newbie to this. I have a load of development kit and a lot of enthusiasm.

I have several esp32-VROOM Modules and understand that I need 2 ADCs as you suggested.

Is there a guide anywhere on how to put all this together and code it?

Thanks

Cost is the lowest of my priorities. While accuracy is not critical why not be fairly accurate, maybe within .1 of a volt. Frequency of reading is important maybe even 5 minutes. The power bank has 7 cells in series. The cells are accessible so a wire can be taken off each cell to the development bo...

The cell balance controller has a serial interface with a cable coming from each cell. The separate cells are easily accessible so it would be no problem for the ESP32 to pick up the 7 voltages.

Hi all. I am very new to the world of the esp32. Is this forum OK to request help with a project? I have a large battery power bank with 7 cells. Each cell voltage is between 3 and 4.5v. I have a charge controller that readball 7 voltages and balances the 7cells. I would like a device that monitors ...
