Which batteries do you have in the mobile, I have 200 amp AGM batteries, I had gel batteries on board before that, they weren't good, they often only lasted a year, I've had the AGM for three years, I live on the mountain, I have to drive a lot of inclines, even in winter Public transport is taboo for me because of safety. I wanted to get lithium batteries but I have no idea how they behave under load and under the influence of weather.
I have 200 amp AGM batteries Don't think the lithium batteries would be any good due to they need to be temperature controlled and if we have cold weather it will. not work properly. I think the gel batteries are your best
