We’ve been using the battery in our coach for 6 months and I have been extremely happy with its performance! We heavily rely on the battery, and it has not let us down. While some extra capacity would be nice, 400 has been adequate. We took delivery of our coach in June, and have been traveling since. I had some initial trouble fitting the battery in the coach. I was short a half an inch of vertical clearance in the battery compartment. I ended up running a long 4/0 cable to a different storage bay. Calculations and rough tests show a 2% voltage drop at 150A, which I am satisfied with.
I set up my system with a Magnum inverter/charger and added a outback solar charger with 960 watts of panels. When the sun is shining and we’re not in the shade, we have all the power we could ever need. With no solar and minor conservation, we can go just over 2 days before having to start the generator. In six months, we’ve run the battery down to 10% twice.
