Your RV’s battery bank is the backbone of your off-grid power system. From lights and appliances to solar charging and inverters, the type of battery you choose determines how far — and how comfortably — you can travel.
Flooded Lead-Acid (FLA)
An old workhorse using liquid electrolyte. Affordable but heavy, high-maintenance, and prone to sulfation. Typical lifespan: 300–500 cycles.
Absorbent Glass Mat (AGM)
A sealed, maintenance-free option. Resistant to vibration and spills, but still limited by voltage drop and shorter cycle life (400–800 cycles).
Lithium Iron Phosphate (LiFePO₄)
The modern choice for serious travelers. Offers 3,000+ cycles, 100% depth of discharge (DOD), lighter weight, and steady voltage throughout use. Integrated BMS ensures thermal and current protection. Higher upfront cost, but lower cost per cycle over time.
Why It Matters
A LiFePO₄ upgrade means faster charging, longer lifespan, and better compatibility with solar systems. For those who rely on their RV for adventure or full-time living, lithium is the power source that delivers freedom — without compromise.
