Budget is a big consideration because I would much rather be putting money into expanding my 24 volt battery bank. I currently have 100ah of 24 volt. I have a 15 amp solar charge controller charging my current SLA with the 24 volt system as the source. It's an RV so I need the 12 volt to run the lights, slide out, Happy Jack bunk, furnace etc. Theoretically I only really need the battery if I ever go beyond the 15 amp of the charge controller. I'm leaning towards SLA because I could still charge with alternator with no modifications. Budget is $100 or less. Concern with going lifepo4 is cold weather at that low price wouldn't have charging cut off. I'm thinking that SLA would last really long because it would spend almost all of its time at full charge. I know it's really stupid that I spent so much time thinking about this question. Your help is appreciated lol.
