Hello
I am using a solar to directly charge a battery through a diode from solar panel and battery. The voltage is 14v from solar panel to 13.3 to battery. This is not the issue.
FROM the schematic you can see the ground from the battery is not being referenced by R2 and R3. Which sould give the voltage indication of the battery to OPAMP pin2. Pin3 voltage is set so that OPAMP output is 0 when battery desired voltage is reach.
The ground from the battery is not being referenced by R2 and R3, there I am not getting good voltage division. I cannot short both grounds for obvious reasons. Anyone has an Idea to get around it ?
