  1. I'm wondering if you could help me with a question about using a low voltage controller on a 12 volt car auxiliary circuit. The set up I have is this: A 12 volt auxiliary battery that provides power for a 12 v fridge. The auxiliary battery is charged via the alternator and a solar panel. I want to put a low voltage controller into the circuit so that the battery does not get drained below 11 volts. I have purchased a control unit but I am concerned that the wiring for the fridge is too heavy for the small controller to wire it directly into the circuit. What I am wondering is can I wire the low voltage controller through a relay that would turn the power on and off to the fridge? I assume that I would need to put some sort of electrically controlled switch that the relay would activate.
