The ARB Slimline 100 12v/100Ah lithium iron phosphate battery separates itself from regular auxiliary batteries, as its low profile allows it to be hidden away in spaces less often used in the vehicle giving you more space to carry what matters most on your travels. Engineered to be an all-in-one solution, the ARB Slimline 100 is supported by vehicle specific mounting brackets and wiring looms.
These accessories, along with its built-in DC-DC charger, facilitate easy installation and a smaller space footprint. Power your fridge, camping lights and other essentials with ease – with the ARB Slimline 100.
Powered Anytime, Anywhere.
Our Engineers have worked tirelessly to take the notion of off-grid power and put the ARB spin on it to reimagine a compact full-featured auxiliary battery solution.
Redefining what it means to have auxiliary power when you’re away from home, the ARB Slimline 100 makes installing, powering and monitoring your battery easier than ever before.
Experience the ARB difference and power your off-grid adventures with ease.
ARB have reimagined fuse replacement to make the often tedious process as simple as possible. The Slimline 100 features an easily accessible and removable window which makes the process seamless.

The Slimline 100 features four reinforced mounting holes that allow for simple installation via the four M8 bolts provided, ridding the need for any additional brackets, saddles or clamps.
Engineers have included a branded PC cover for the terminals to ensure extra protection for your connections and cords running to them.
Power switch has been added in to cater for safe installation.
Connection to the terminal can be achieved from different angles to allow for flexibility when installing, taking up as little space as possible.
Safety and durability are at the forefront of development of the Slimline 100, being powered by high-quality lithium-iron phosphate cells sourced from a leading manufacturer to meet rigorous standards and obtain certification for extensive Australian and International standards.
Engineers have elected to use bolted joints for electrical connections on the Slimline 100 to provide a more reliable connection for a higher discharge current. Connecting all your essentials in this design also allows you to control the direction of cables to reduce the overall footprint of the battery.
LED lighting has been included to provide live visual indications of the Slimline 100's status.
A major feature of the Slimline 100 is the ability to select between obtaining input from either an indications alternator or 12V solar panel.
The Slimline 100 features an in-built BMS that protects the battery cells from reasonably foreseeable misuse and monitors the battery’s operating status.
The inbuilt DC-DC charger ensures optimal battery charging, prevents overcharging, and eliminates the need to purchase an external charger for your setup.

**Test conducted on a 44L ZERO fridge freezer. Ambient temperature: 25°C, fridge set to 4°C.
*An Absorbed Glass Mat (AGM) lead-acid battery is recommended to be discharged to 50%, while ARB suggests for the Slimline 100 Lithium Iron Phosphate Battery an 80% depth of discharge to extend its cycle life.
*Please note that the information provided is intended for reference purposes only, results will vary depending on multiple contributing factors.
*When used in conjunction with a compatible inverter, will enable you to power selected 110/240Vac appliances such as your toaster, induction cooktop and other popular appliances.
An auxiliary battery system prevents the main battery from discharging when using 12V or 240Vac devices, such as high-power appliances at camping sites. It also reduces reliance on gas generators, addressing environmental concerns.
Lithium batteries are lighter (half the weight of AGM batteries), have six times the cycle life, handle heavy loads efficiently, offer comprehensive fault protection, and include built-in battery capacity in premium lithium models.
Slimline batteries are ideal for vehicles with limited engine bay space, allowing installation in compact or unused areas such as behind the rear seat or under a drawer.
A slimline battery with a built-in DC-DC charger simplifies installation by eliminating the need for a seperate mounting bracket, reducing wiring complexity and saving space.
ARB provides a complete solution with the battery, mounting bracket and wiring harness. This integrated approach means you don’t need to shop for individual parts, making it easier to complete your auxiliary battery system. The ARB Slimline 100 features lightweight Lithium Iron Phosphate (LiFePO4) cells, high power handling, advanced charging capabilities and comprehensive safety features. It also includes an app for easy monitoring, enhancing the off road experience and preserving the main vehicle battery’s health.
No, mixing different batteries can affect charging performance and overall capacity.
Yes. Multiple Slimline 100 batteries can be connected in parallel to increase capacity.
The Slimline 100 has a 100Ah capacity (1280Wh) and can handle up to 200A discharge for 20 minutes, making it suitable for devices like 2000W coffee machines, induction cookers, and other lighting and charging needs.
