Stay fully charged

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.

Put the power back in your hands

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.

Slimline 100 battery FAQs

  • Why do we need an Auxiliary Battery System?

    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.

  • Why choose a lithium battery over a lead acid AGM battery?

    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.

  • Why do I need a slimline battery?

    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.
