Lithium (LiFePO4) Batteries: The Future of Off-Grid Power.

Upgrade your motorhome, caravan, or boat with the ultimate in power technology. Lithium Iron Phosphate (LiFePO4) batteries have revolutionised the New Zealand RV market, offering a high-performance alternative to traditional lead-acid and AGM batteries. If you are a frequent freedom camper or rely on power-hungry appliances like 12V fridges and diesel heaters, lithium is the most efficient and cost-effective long-term investment you can make.

At RV World, we stock the most reliable lithium brands in NZ, including Enerdrive B-TEC, Artemis (Standard & Gold Series), and Sterling Power, with capacities ranging from 60Ah to massive 300Ah units.

Why Make the Switch to Lithium?

Lithium batteries outperform traditional batteries in almost every metric, providing a "home-away-from-home" power experience:

• Lighter Weight: Lithium batteries are roughly 50% lighter than equivalent AGM batteries, helping you stay within your vehicle's GVM (Gross Vehicle Mass).
• Faster Charging: They can accept a much higher charge current, meaning your solar panels or DC-DC charger will replenish your power bank significantly faster.
• Superior Usable Capacity: While AGM batteries should only be discharged to 50%, you can safely use up to 80-90% of a lithium battery’s capacity without damaging the cells.
• Extended Cycle Life: A quality LiFePO4 battery can last for 2,000 to 5,000 cycles—up to ten times longer than a standard deep cycle battery.

Smart Technology & Safety Built-In

All our lithium batteries feature an integrated Battery Management System (BMS). This internal computer acts as a safeguard, protecting the battery from over-charging, over-discharging, short circuits, and extreme temperatures. Many of our premium models, such as the Enerdrive B-TEC G2 and Artemis Gold Series, also feature integrated Bluetooth, allowing you to monitor your battery’s state of charge, voltage, and health directly from your smartphone.

Is Your Charging System Lithium-Ready?

To get the most out of your investment, it is essential that your charging components (AC chargers, Solar Controllers, and DC-DC chargers) have a dedicated Lithium profile. Using an old lead-acid charger can result in incomplete charging or even damage to the cells. Browse our range of lithium-ready chargers and monitors to complete your system upgrade. Experience true energy independence on your next New Zealand adventure with a high-capacity lithium house battery.
