Question:
So Im turning my enclosed car hauler into a semi-camping trailer. My trailer came with a breakaway battery that Id like to keep charged along with my completely separate deep cycle battery that will run my lights and a few small accessories. What Im looking to do is permanently attach a 12v solar panel kit with a dual battery charge controller. From what Ive noticed it that most dual battery charger controllers are 20A-40A. Can I just hook up the breakaway battery to one of the battery charge ports and the separate deep cycle battery to the other charge port? Or would I need a resister of some sort in line with the breakaway battery?

Expert Reply:
When hooking up both your deep cycle 12V battery and breakaway battery to a solar panel controller you shouldn't need to add a resistor in line between the two batteries. When using a controller that features dual battery profiles like the Go Power # 34276119 there won't be any concern with the breakaway battery draining.
A 100 watt panel like the Overlander Charging Kit # 34272635, which includes the above-mentioned controller, should be sufficient to keep both batteries charged according to my contact at Go Power.
