Best RV Batteries
Your RV house battery powers everything when you're not plugged in — lights, water pump, fridge, USB chargers. Lithium (LiFePO4) batteries have largely replaced lead-acid for serious RVers: they're lighter, last 5-10x longer, and can discharge to 80-100% vs only 50% for lead-acid.
