All this talk of freezing cold temps makes me want to put a jacket on, I live in Southern California, I put 4, 100 watt solar panels on my 25.4 Axis and 4 group 29 Gel Cell Batteries, they are Renogy batteries and Panels, the batteries were $350.00 each from Amazon and the rep from Renogy tells me I should get 10 years out of these batteries, all lead acid batteries have average life span of 6 years and they average about $100.00 each, anyone have any long term experience with Gel Cells? Gel Cells are truly maintenance free, so far they have been good to me but I doubt I get the 10 years out of them. the solar panels have just about put my generator out of business.
