NICE ! maybe my 3 deep cycle coach batteries will run the heater longer than i thought! good to know.
how are you measuring your battery voltage? I added a small
12v panel meter like this $8 dollar one
I have one of those 12vdc panel meters outside too....next to the outside TV / Entertainment system.
