My goal is really to get heat out of my Espar for 8 hours ( 4 cycles of the heater) I just need the van to start again in the morning. Also, I don't mind running a high idle half hour in the middle of the night if I need to.
I have installed a battery isolator and a used deep cycle battery (may need replacing) under my right seat. The most important electrical loads (espar and water pump) are still on the starting battery under the hood. I need to get those loads transfered to the deep cycle battery before it gets too cold. As I have been thinking about how to do this, I wondered, might it be easier to just switch the batteries, putting the starting battery under the seat and the deep cycle battery under the hood, then switching the cables at the isolator?
Thoughts?
