WOW, didn't mean to start a fire. Just want to cut back on gen run time while dry camping & keep the batt up while stored in the back yard between trips. Like I said I have dry camped for over 16 yrs with no solar and have had good life with my batt. I had no idea there was so much science in this simple addition to my gen. I had 2 grp 27 marine/deepcycle's last 6 yrs. How long should they last?
BTW would 6/8' be too far between controller & batt?
