I have lipo battery with 8 cells so total voltage is 33.6V
Now I need to measure each cell and when first one drops to 3.8V when discharge relay will turn off.
Problem is now how to measeure each cell because they are serial connected.
I thought to use Cmos 4097 which has 2 x 8 channels to switch between cells.
problem is because power voltage of 4097 is 12V and battery from first to last cell is 33.6V.
That will burn 4097.

Any idea how to solve this?
