How is the RV lithium battery conversion kit shipped? Will everything arrive together?
Each component in the RV LiFePO4 lithium converstion kit may ship separately depending on size and availability.
We offer free standard shipping on all orders, and items typically arrive within 2–5 business days.
What if it rains and there’s no sunlight — how do I charge the battery?
You can charge your battery in two ways:
- Via vehicle alternator using a DC-DC charger (sold separately)
- Via shore power (AC outlets) at RV parks or home using an AC-DC charger (Note: our Extreme Overlander battery conversion Kit includes an all-in-one inverter/charger — no additional charger needed.)
What should I know if I plan to expand my power system later?
To ensure safety and optimal performance when expanding your power system:
- Use the same battery brand and model for all additional batteries. This ensures voltage and chemistry compatibility.
- Purchase additional batteries within one month of your original purchase to minimize differences in battery age and performance.
- Consider adding a DC-DC battery charger, especially if you want to charge from your vehicle alternator. This is particularly useful in rainy or cloudy weather when solar input is limited.
A well-matched, properly expanded system will give you more flexibility, faster charging, and longer off-grid runtime.
What is included in an RV lithium battery conversion kit?
Weekend Camper Kit(About 2 days of basic camping): 2 × 12V 100Ah Slim batteries, 40A DC-DC charger with MPPT, 2000W 12V pure sine wave inverter, 500A monitor with shunt, 250A circuit breaker, and 4 AWG battery cables.
Family Trip Kit(3–5 days of moderate off-grid use): 2 × 12V 165Ah batteries, 3000W inverter, and 60A MPPT-based charging components.
Long-Haul Pro Kit(Long-term travel and high-load appliance use): 2 × 12V 320Ah Mini batteries, 3000W inverter, and 60A MPPT setup, with about 8.2kWh of battery energy.
Is a RV battery conversion kit better than buying parts separately?
A RV lithium battery conversion kit can save time because the major parts are selected to work together. This is useful if you are not comfortable matching cable sizes, charger ratings, fuses, and battery capacity on your own. A kit can also reduce the chance of missing small but important components.
