Yes and no. I saw a chart giving cycle life vs depth of discharge for AGM batteries- see attached. At 50% you get 1,000 cycles. At 80% you get 500 cycles. How many of us camp 500 times during say a nominal 5 yaar life of your batteries.
I too have two new 100 Ah Windy Nation AGMs installed. If we camp only three days at a time our batteries should stay above 50%. But I am not worried about camping a 4th or 5th night every now and then and discharge them well below 50%.
