Lithium Battery Safety and Diesel Heater Installation in Caravans: Ensuring a Safe Journey

Traveling in a caravan offers a sense of freedom and adventure. However, ensuring your vehicle is safe and up to date with the latest electrical standards and heating solutions is crucial. In this blog, we will discuss the new electrical standards for recreational vehicles and share insights on safely installing diesel heaters in your caravan.

Understanding the Latest Electrical Standards for RVs

On 18th November 2022, Australia introduced a new standard series - AS/NZS 3001 ELECTRICAL INSTALLATIONS – CONNECTABLE ELECTRICAL INSTALLATIONS AND SUPPLY ARRANGEMENTS. This standard took full effect on 18th November 2023. It's important for caravan owners to understand which standards apply to their vehicles. If your caravan was completed before 18th November 2023, it must comply with the 2008 standard; if it's completed after this date, the 2022 standard applies. It's worth noting that both standards ensure safety, with the new standard offering incremental improvements in safety and best practices​​.

Lithium Battery Safety in Caravans

With the advent of the new standards, there are specific considerations for battery installations, especially lithium batteries. The commonly used Lithium Phosphate (LiFeP04) batteries in RVs are inherently safe and have a long track record. The new standard takes a conservative approach to all battery installations, ensuring enhanced safety for caravan enthusiasts​​.

When installing lithium batteries in your caravan, it's important to consider both safety and efficiency. Here are some key guidelines for the optimal placement of lithium batteries:

  1. Away from Living Areas: Place the batteries in a location that is not within the main living or sleeping areas of the caravan. This helps reduce the risk of any fumes or hazards affecting the occupants.

  2. Ventilation: Ensure that the area where the battery is installed is well-ventilated. Lithium batteries, while generally safe, can produce heat and, in rare cases, emit gases. Adequate ventilation helps dissipate any heat and gases.

  3. Accessibility for Maintenance: The installation spot should be easily accessible for regular maintenance checks and emergency access if needed. It's important to regularly check the health of the battery, its connections, and its housing.

  4. Stable and Secure Location: The battery should be mounted on a stable and level surface to minimize movement or vibration while the caravan is in motion. It should be securely fastened to avoid any shifting, which could lead to damaged connections or short-circuiting.

  5. Away from Heat Sources: Keep the battery away from direct heat sources such as heaters or stoves. Excessive heat can affect battery performance and longevity.

  6. Protected from the Elements: Ensure that the battery is installed in a location where it is not exposed to moisture or extreme temperature changes. This could be in a dedicated battery compartment or an under-seat storage area that is insulated and protected from external elements.

  7. Compliance with Standards: Follow the guidelines provided by the battery manufacturer and ensure compliance with any relevant local or national standards for electrical installations in recreational vehicles.

Remember, the installation of lithium batteries in a caravan should be done considering the overall balance of the vehicle's weight and distribution. If you are unsure about the best location or have specific concerns about your caravan's layout, it’s advisable to consult with a professional technician or the caravan manufacturer for guidance. This ensures that your installation is both safe and compliant with any relevant standards or regulations.

Installing Diesel Heaters in Your Caravan

When it comes to heating your caravan, diesel heaters are a popular choice due to their efficiency. The ideal location for these heaters is usually under a seat or bed, ensuring good airflow for the heater and allowing warm air to be ducted out effectively. It’s crucial to choose a flat, level surface for installation and to keep the heater away from flammable materials​​.

Ensuring Proper Ventilation

Proper ventilation is essential when using diesel heaters. These heaters need to be vented to prevent the build-up of harmful gases produced during diesel combustion. Ensuring the exhaust pipe is securely connected and positioned outside the caravan is vital. Regular inspections of the exhaust outlet for obstructions are also recommended for ongoing safety​​​​.

Maintenance and Safety Tips

Regular maintenance of your diesel heater is key to ensuring its safe operation. This includes monitoring the exhaust gases and clearing any blockages in the exhaust outlet. Always consult with a qualified electrician or the Electrical Safety Regulator in your jurisdiction for any alterations or repairs to your caravan's electrical systems​​.


Staying informed about the latest electrical standards and understanding the proper installation and maintenance of diesel heaters are crucial for safe caravan journeys. By adhering to these standards and safety tips, you can enjoy your travels with peace of mind, knowing that your vehicle is safe and compliant.
