The best lithium batteries for camping in Australia

A 100Ah lithium battery is the heart of most 4WD and camper trailer power setups: it runs the fridge, lights and a small inverter, and a DC-DC charger fills it while you drive. Every battery here is LiFePO4, the safe, long-life lithium chemistry used for deep-cycle batteries. Prices are from Snowys, BCF, Anaconda, iTechworld and 4WD Supacentre on 18 October 2026; for models on Amazon Australia, check the current price on Amazon. We compared maker specifications and retailer listings; we have not cycle-tested these batteries.

Five numbers that matter

Capacity, and the rate behind it. Hardkorr rates its Black Series at C5: 20A for five hours. iTechworld and Renogy rate at C20, the gentler 20-hour test. A C5 rating is the harder test to pass, and Hardkorr calls its figure a true rating with no inflated nominal numbers.

Cycle life, and the depth behind it. Hardkorr and iTechworld quote 5,000+ cycles at 80% depth of discharge. Kings quotes 2,000+ at 80%. WattCycle’s Amazon listing quotes up to 15,000 cycles with no depth stated, which cannot be compared with the others.

Continuous current. This decides the inverter you can run. Hardkorr allows 100A and says its battery comfortably runs a 1,000W inverter; iTechworld allows 150A continuous on both its 105Ah and 120Ah batteries.

The battery management system (BMS). All seven have one. What differs is what it tells you: Hardkorr and iTechworld add app or Bluetooth monitoring, so you can see charge, current and, on the Hardkorr, cell temperature.

Cold-weather charging. Every maker here that publishes a charging range starts it at 0°C or above, which is why a battery in a freezing canopy can refuse to charge. Dune gives a charging range of 0 to 50°C. iTechworld gives an optimum range of 5 to 60°C. Kings says its BMS disconnects on under-temperature but gives no figure. Hardkorr, Renogy and WattCycle do not state a charging range on the pages we read. If you camp in the alpine country or the desert in July, ask before you buy.

The comparison

The Kings 100Ah (bundled with a worklight) and the WattCycle 100Ah are sold on Amazon Australia; check the current price on Amazon.

Will it fit?

Most 4WD battery trays and boxes are sized for a Group 24 (N70) AGM. The Hardkorr (260 x 168 x 209 mm), Renogy (260 x 169 x 211 mm), WattCycle (26 x 17 x 21 cm) and iTechworld 105Ah (255 x 170 x 215 mm) fit that footprint. The 120Ah batteries from iTechworld and Dune are 330 mm long and need a bigger tray. Measure before you order.

The picks

The Hardkorr Black Series 100Ah is the one we would buy. Its capacity is rated at C5, it is certified to IEC 62619 and UN 38.3, rated IP66, quotes 5,000+ cycles at 80% depth of discharge, and the HK app shows charge, current, temperature and cycle count. It weighs 9.7 kg, fits a Group 24 tray and carries a five-year Australian warranty. It was $359 at Snowys on 14 November 2026.

The iTechworld iTECH120X 105Ah is for bigger loads: 150A continuous, 430A for five seconds, IP67 and Bluetooth, at 10 kg, for $459 at iTechworld and Anaconda on 14 November 2026. Its warranty is five years, the last two pro-rata. The iTECH120X PRO adds 15Ah for $120 more ($579), in a longer case.

The Dune 4WD 120Ah is the most battery for the money at $299, with named EVE grade A cells, IEC 62619, IP65 and a published 0 to 50°C charging range. It gives no cycle rating and carries three years of warranty.

The Renogy 12.8V 100Ah at BCF ($399) is a plain, standard-size battery with a 100A BMS and IEC 62619, but no Bluetooth and a pro-rata warranty. The Kings 100Ah is the same price at 4WD Supacentre and sold on Amazon by 4WD Supacentre, but its one-year warranty and 2,000-cycle rating are well behind the rest.

Charging it

Lithium batteries need the right charger. From the vehicle, that means a DC-DC charger with a lithium profile; Redarc pairs its 40A units with lithium banks over 100Ah. At camp, add a solar blanket or panel through an MPPT regulator. Size the battery to your fridge first: our 12V fridge guide lists each fridge’s published draw.

Safety and installation

A loose battery in a vehicle is dangerous in a crash, so mount it in a proper tray or battery box with tie-downs. Wiring a second battery into the vehicle, running cable from the starting battery, fitting fuses and an isolation or DC-DC charger, is a job for an auto electrician. A battery box with a plug-in DC-DC charger can be moved between vehicles, but its connection to the vehicle still needs correctly sized cable and fusing.

If you would rather wire nothing, a portable power station does the same job at a higher price per watt-hour.

The one trap

Comparing cycle numbers that are not measured the same way. “15,000 cycles” with no depth of discharge, “5,000+ at 80%” and “10,000+ at 40%” (iTechworld’s second figure for the same battery) describe very different lives. Compare batteries only at the same depth, and give weight to the warranty: it is the one cycle claim the seller has to pay for.
