Not sure about a mini-split cycling down with the typical poorly insulated RV. But if a 4A 120V unit does the job then for 12V use a 11x multiplier. So 44Ah for 1 hour and 440Ah for 10 hours. For flooded batteries 880Ah with a 50% discharge would work. Thats 8 6V GC2 deep cycle batteries weighing about 500 lbs.
Thats great - err oh wait - It's day 2 and I now have to recharge the batteries... Gens looking better...
Ha, I get your point, but how long do you think it would take to charge that battery bank with a generator? If I'm staying in a National Park and limited to generator use during the day, it still solves my problem of having air conditioning overnight!
120MM 12V computer case fan like above does a pretty swimmingly well job of moving air around while sipping your battery power..
Careful selection of those fans can get you noise levels of 40 DB or less but get you 100 CFM of air movement all the while using 12W or less.. The key to quiet is to look for low RPM models under 3,000 RPM.. Of course, you will need to buy some fan grill guards for each side but those can be had for low cost also.
While not as nice and comfy as A/C, it is an improvement over hot muggy nights with no natural air movement and no generator or additional batteries required..
