Not sure if it would be appropriate for Wisconsin if the cabin gets well below freezing for longish periods of time. If it were me, I'd probably be willing to try it just as an experiment. That's essentially what I did considering I had no other examples of people doing what I had done.

I actually ran this exact battery for 2 winters in Vermont. The first winter I had supercaps starting the engine and the battery sat behind a very low ohm resistor, just to keep the caps topped off. Second winter I just used it as a starter battery, and it held up.
Not that I advise this.
LiFePO4 isn't going to explode from mis-treating it, but it's an expensive battery to kill.
