Anyone used the likes of this:

I have heard that starting and deep cycle batteries have differing charging preferences, hence the fancy doodad battery control systems out there I suppose.
But for 15 years one the sailboat we just used the good old rotary battery selector and we never had problems (that I am aware of).
So this rectifier seems even simpler. Thoughts?
