Looking for suggestions. I am looking at installing 20 LiFePo4 cells (180-200 AH cells) for somewhere between 900 AH and 1000 AH at 12v in a power hungry (residential fridge etc) motor home that already has 1100 watts of solar and a Midnite Solar 150 controller.

I have heard good good things about the Orion Jr but it is only good for 16 cells. What retail options are available that would work for such a system with 20 cells?

Thanks for any suggestions.
