@Gary posted:We just watched 2 hrs of sat Tv with lights on. 2 cheap group 27 5 yrs old flooded batteries and the control still says 12.6 . In the morning with the furnace set at 58 degrees it will say 12.5 then the sun will be up and in a few hours fully charged. I have to wonder why spend lots of money on lithium when the old technology works so good
Somehow I don’t think your two cheap Group 27 batteries would fit into my chosen dry camping lifestyle. And I couldn’t get 5 years out of my last set of AGM batteries - At 3 years they were not holding a charge as well as they had when new - I don’t think they would have lasted another year. The lithium batteries that replaced them were in their third year when I traded the 1685 in and the batteries were holding a charge as well then as they did when new.
This new trailer uses a little more power than my old one did. I’ve been dry camping for 10 days and have used around 75-85Ah each night (one night was 116Ah - forgot to turn off the inverter when I went to bed).
So for me, your old technology doesn’t work so good.
