REDARC Electronics acknowledge and fully support the new standard introduced in AS/NZS3001.2:2022, which address various aspects of the electrical system safety in RVs (Caravans, Motor Homes, and Camper trailers). This standard is driven by a collective commitment to enhancing safety of the installation of electrical systems, including batteries.
Several REDARC products require specific installation methods and considerations to achieve compliance with the standard, including inverters, solar panels, fuses, wiring and batteries.
The following FAQ focusses on the specific requirements relating to battery installations outlined in AS/NZS 3001.2:2022.
FAQS
What is the new standard?
AS/NZS3001.2:2022 outlines requirements and guidelines for various aspects of the electrical system in Caravans, RVs, and Camper trailers. The standard considers wiring, inverters, solar panels, and batteries. The standard also requires batteries to comply with AS IEC 62619.
What is driving the change in standards?
The change in standards is driven by the need to improve safety and consistency in the storage of batteries in RVs. The new standards, AS/NZS3001.2:2022, have been developed in consultation with electrical experts and industry professionals to address safety concerns and ensure standardization in the industry.
When are they enforced from?
The new standards are enforceable from 18 November 2023.
Who does it apply to?
The standards apply to everyone buying or using a new recreational vehicle build but are of particular importance to manufacturers and importers of recreational vehicles.
Do I need to comply to the new standard?
The standard applies for any new installations from the 18th of November 2023 (the effective date). The new standard applies to any new electrical installations (vehicle builds) conducted after the effective date, but not to existing installations. Installations prior to the effective date will be assessed against the standards at the time of installation so long as they meet basic safety standards.
Typically, repairs may be conducted using methods, fittings and fixtures that were acceptable at the time of the original installation. Alternatively, currently available methods fittings and fixtures available as direct replacements may be used, providing that basic safety requirements are met.
Alterations, e.g. replacing lead acid batteries with lithium batteries, are to be completed in line with the current (new) standards and shall not compromise the remainder of the installation.
REDARC recommends consulting a professional and ensuring the installation complies with the new standard.
Will it affect my existing installation?
The new standards are enforceable on new RVs, so they are unlikely to affect your existing installation. However, if you plan to make any alterations or updates to your RV's electrical system, including battery system, it is advisable to consult with a qualified professional to ensure compliance with safety standards.
In a nutshell, what are the key changes?
The key changes include requirements for the installation, mounting and wiring of electrical systems into RVs including inverters, solar, wiring and batteries. With respect to batteries the changes focus on minimising the potential for adverse events by considering protection against harmful gasses and fumes and to prevent their build up, fire, damage from water ingress, damage from physical impact and to make sure they are installed and operating withing the batteries specifications.
What REDARC products does it affect?
The new standards will affect the REDARC Lithium battery range, when installed in recreational vehicles.
LBAT12100, LBAT12100-HD and LBAT12200 (Note: LBAT12150-SB does not comply with AS/NZS 3001.2:2022)
Do REDARC lithium batteries comply with the new standard?
The LBAT range of REDARC batteries, except the LBAT12150-SB, comply with IEC62619, a requirement of the new standard. If these REDARC batteries are installed in accordance with the regulations, they are considered to be meeting the standard.
What do the standards say about lithium batteries in caravan/camper trailers?
The new regulations stipulate that a lithium battery cannot be installed in a habitable living area, such as inside a caravan or camper trailer, unless it is placed in a sealed enclosure, or the installation location is sealed off from the habitable area and the sealed off area is vented to the exterior environment.
How do I get a copy of these regulations / can you send me a copy of them?
You can obtain a copy of AS/NZS3001.2:2022 by purchasing it from Standards Australia.

Can the batteries be mounted on the outside of the caravan (i.e. Chassis)?
Yes, as this is not classed as a habitable environment, lithium batteries can be mounted on the exterior of the caravan. When installing outside the vehicle it is important to ensure that the installation ensures the batteries are operated within their specifications. The installation must be protected from physical damage, operating within its temperature range, adequately IP rated to protect against water and dust etc.
How do I install batteries within the standard if the batteries are to be mounted inside the caravan?
When installing batteries inside the caravan while adhering to the standard, it is essential to place the batteries within a sealed enclosure, with venting directing gases outside of any habitable areas whilst also ensuring that the enclosure (venting port) is environmentally protected. The enclosure must provide access for installation and maintenance and must have effective seals. A screwdriver or special tool must be required to access the enclosure. Whilst the standards do not provide specific guidance on the material that should be used to construct this enclosure it should be suitable to provide a sturdy home for the batteries and survive the roads conditions that the Caravan/RV is designed for.
If I change out my factory fit AGM to Lithium does it need to meet the new standard?
If you replace your factory-installed AGM batteries with lithium batteries, REDARC recommend you ensure that the new installation meets the new standards for safety and compliance. Consult with a qualified professional to ensure your conversion complies with the standards.
What’s the difference between Lead Acid and Lithium battery installations?
Lead acid (LA) batteries are also required to be sealed off from the habitable area and to be vented externally. Because LA batteries release gasses that are lighter than air they need two vents, one at the top and one at the bottom of the enclosure. An enclosure that is design specially for Lithium batteries, i.e., one has one vent must be clearly labelled as only being suitable for lithium batteries and to not install LA batteries in the enclosure.
Are lithium batteries safe to use?
Lithium batteries with an in-built BMS that monitors and balances individual cell voltages, monitors charge voltage and current and ensures the battery does not drop below an acceptable charge level are safe to use when installed and maintained correctly.
What are the repercussions of installing non-approved lithium after Nov 18?
As with any non-conformance to Australian Standards, the vehicle in question can be defected and any manufacturer or importer of non-compliant vehicles may be prosecuted to the extent of the law.
What about in-vehicle situations? Can batteries be installed in-cabin or in the engine bay still due to these standards?
The changes to AS/NZS 3001.2:2022 do not explicitly consider in-vehicle installations unless they are installed in a habitable area, however the recommendations on installation including gas venting, fire, physical and environmental protection are still valid for all installations.
