Lithium Batteries in Caravans, Motorhomes and RVs: AS/NZS 3001.2:2022, IEC 62619 and the Off-Grid Fire Risk Everyone Forgets
The Australian caravan and RV scene has gone lithium. LiFePO4 house batteries are now standard on most new vans, and tens of thousands of older lead-acid setups have been retrofitted in the last few years. Lighter, smaller, faster-charging, longer-lasting — the case for upgrading is genuine. But behind the upgrade is a new wave of Australian Standards (AS/NZS 3001.2:2022), a quietly mandatory international certification requirement (IEC 62619), and a real fire risk profile that many caravan owners and dealers underestimate.
Caravan parks across NSW, Queensland, Victoria and WA have all reported lithium-linked van fires. Insurers are tightening up. And the riskiest battery on board your van is often not the one you bought — it's the one you forgot about.
This post is for caravan and motorhome owners, dealers, holiday park operators, and anyone doing a big lap with lithium-ion in the back.

What the standards now require
AS/NZS 3001.2:2022
Effective from 18 November 2023, this standard governs electrical systems in caravans, motorhomes and camper trailers. Key changes for lithium installs:
- Batteries must be installed in a way that prevents gas egress into the habitable area
- Enclosures must protect against physical impact and water ingress
- Battery compartments must be properly vented and labelled
- Mounting, wiring, fusing and inverter requirements are all tightened
- Lithium-only enclosures must be clearly marked to prevent lead-acid being substituted in
The standard isn't retrospective — vans built or modified before 18 November 2023 are exempt. But the moment you upgrade, replace, modify or add to your electrical system, the new standard applies.
IEC 62619
This is the international safety standard for lithium batteries in industrial applications, including RVs. It tests battery packs under stress conditions — heat, shock, short circuit, overcharge — and ensures the entire pack (not just the cells) is built to fail safely. Most states now reference IEC 62619 through their electrical safety regulations, effectively making it mandatory for compliant RV lithium installs.
If you're buying a new battery for your van, ask the supplier for the IEC 62619 test report for the whole pack, not just the cells inside it.
Where the actual fire risk sits
Australian fire services have been clear about this: the spontaneous-combustion fires you read about in the news are almost never caused by quality LiFePO4 house batteries professionally installed under the new standard. The fires come from:
1. The other lithium-ion you've brought along
Phones, laptops, e-bikes, e-scooters, drones, cordless tools, jump starters, power banks, electric coolers, hair tools, toothbrushes, headphones. A modern caravan rolls around the country with 20+ lithium-ion devices on board — most charging unattended, most overnight, most in a confined space.
2. Cheap, non-compliant aftermarket battery packs
Knockoff replacement batteries for major-brand tools and devices, bought online, often without RCM marking. Internal build quality is wildly variable, and these are heavily implicated in fires.
3. Mismatched chargers
"This one fits" is the classic ignition story. Always use the original charger that came with the device.
4. Physical damage from rough roads
Repeated vibration and impact can degrade battery casings over time. Off-road and corrugated-road usage compounds this.
5. Water ingress
River crossings, downpours, condensation in poorly-vented compartments. Lithium-ion cells and water don't mix.
6. Heat exposure
A van stored in full sun in summer can hit 60°C+ internally. Repeated thermal cycling accelerates cell degradation.
What a real lithium-ion fire in a van looks like
A van fire involving a lithium-ion battery typically progresses:
- Off-gassing begins — flammable, toxic vapour fills the cabin before any flame
- Detection often happens via smell (sweet, chemical) or by the BMS shutting down
- Within minutes, ignition follows — often dramatic and explosive
- Temperatures climb past 1,000°C
- Adjacent cells cascade into the same runaway reaction
- The van is almost always a total loss within 10-15 minutes
The reason caravan fires destroy vans so completely is the confined space — there's nowhere for the heat and gas to go, and the lightweight construction provides plenty of fuel.
Practical safety setup for a lithium-equipped van
For your house battery system
- Buy IEC 62619-certified packs only, from reputable Australian brands
- Have the install done by a qualified auto-electrician who knows AS/NZS 3001.2:2022
- Get a written compliance certificate for resale value and insurance
- Inspect the battery compartment annually — look for swelling, heat marks, water ingress
For everything else with a battery in it
- Charge during the day, supervised, when possible
- Charge outside the van when feasible (an awning table, a powered site bench)
- Never charge multiple high-capacity devices unattended overnight
- Keep cheap aftermarket batteries off the van entirely
- Pull damaged or swollen batteries off the van immediately and into a containment bag
Fire safety equipment on board
A van needs three layers — and the standard ABE dry-chemical extinguisher most vans come with isn't built for lithium-ion fires.
- A lithium-ion-rated fire extinguisher mounted near the main entry door, where you can reach it from outside if the fire is inside. Our 1L unit is ideal for vans and small motorhomes. Browse extinguishers →
- An EV fire blanket stowed in an external compartment — large enough to cover the device or area in trouble. Browse blankets →
- A lithium-ion containment bag for any damaged battery you need to safely isolate during the trip — including disposable vapes and dead power tool packs. View containment bags →
Pre-built bundles work out cheaper than buying individually:
For caravan dealers and parks
If you sell or service caravans, your customers are increasingly informed about lithium safety and increasingly worried. Offering a fire safety upgrade as part of a delivery or service package adds margin and demonstrates real care for long-term customer outcomes.
If you operate a caravan park or holiday park, the policy questions are real: where can guests charge e-bikes? Should you have communal charging zones? What happens when a van catches fire on site? A few hundred dollars of fire safety equipment in a designated zone is a small spend against the alternative.
Insurance implications
Australian insurers are paying close attention to lithium-ion. Most policies now ask whether your house battery install complies with AS/NZS 3001.2:2022. Some are tightening exclusions for fires caused by aftermarket or non-certified equipment. If you've upgraded since November 2023 and don't have written compliance documentation, get it before your next renewal.

You don't pack 20,000km of fuel without checking the tank. You shouldn't run 20,000km on lithium without the right safety gear either.
