First, I am new in this topic, so please excuse unnecessary questions.
I want to measure the (four) cells of my lipo battery. The connector of the battery has a plus pole and four minus poles. (Image)
Now I want to measure the cells with the Raspberry Pi, which max. voltage is 3.3 Volt. I use the ADS1115 to add analog pins to the RPi (works well).
So I drawn a schematic for a voltage divider to bring the max. 16.8V to 3.3V (works well)
Now my problem:
How I make the schematic bigger, because if I connect every battery minus to ground I am not able to measure the difference.
I want a different measurement for every cell.
