Idfk why it was closed, but advice to the OP. You’re planning on living in the camper in cold winter weather. First Battleborn batteries are LifePO4 not lithium ion. Second you’re giving up capacity with one 100ah battery compared to even 2 normal 12v flooded batteries. Only savings is weight. The battery and your wallet.
But most importantly, you are in the wrong conditions to use a Lifepo4 battery. They don’t work well in the cold.
You have some more research to do and based on your previous posts, idk how a $1000 battery could be in your budget...subjectively.
Without a serious battery bank and waaay more solar and daylight, you’re not goin to live in the winter without being plugged in. If you don’t have shore power, spend half the cost of what you’re planning on a used Honda generator and a big chain to lock it up.
