Needs a disconnect switch and then you'd have something.

I like the concept - for me, a gauge rather than the LED would be more useful. I mean at 12.7 you are full and green, then you get orange which means the battery has been used. The problem here is that by red, you are done. When you go below 12V you are hurting the batteries but you had no warning on how close you were....
