I use two, 232 amp hour, 6 volt golf cart batteries. I have camped off grid with them many times, in temperatures down to 25 degrees F. I use the furnace, fridge, lights, water pump, charge phones, and watch 8-10 hours of TV per day.
I average about 15% battery discharge (or 85% state of charge) per 24 hour day. I’ve gone three days without recharging with about 40% battery discharge (or 60% state of charge).
60% state of charge is as low as I will take my batteries. Taking them below 50% will damage them and shorten their lifespan.
I highly recommend using two six volt batteries.
