100Ah Capacity
The ARB Slimline 100 provides great outputs when it comes to power and capacity, with 100Ah Capacity (1280Wh) providing sufficient power for off-road adventures. The 100Ah gives you plenty of power to power your fridge, lights and all those electrical devices your kids bring for that weekend away.


200A Discharge for 20 Minutes
Breaking down the Slimline’s 100Ah capacity further, the 200A discharge allows a high-power inverter connected to the battery output to run devices such as a 2kW coffee machine or an induction cooker for up to 20 minutes.


Inbuilt DC-DC
The integrated charging system via inbuilt DC-DC ensures optimal battery health and prevents charge mismatches, whilst also removing the need to buy an additional unit for your setup.


In-Built Battery Management System
The Slimline 100 comes with a Battery Management System in-built in the unit, performing regulation of status in the background to give you peace of mind when powering all your camping goodies.


Bolt Joint Connection
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 orientation also allows you to control the direction of cables to reduce the overall footprint of the battery.


High-Quality LiFePO4 Cells
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.


40A 4-Stage Charging
Smart charging has also been a focus for the team, with the inbuilt 40A 4-stage charger ensures a fast, efficient, and safe charging to the internal battery cells.


Dual Input Options
Dual input options are also included to accept charge from either alternator or solar inputs. This means you can charge no matter your vehicle setup.


Selectable Input Voltage
Engineers have made input voltage on the Slimline 100 selectable, ensuring you don’t overcharge appliances with lower voltage inputs.


Fuse Window
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.


Mobile App
The Slimline 100 even has its own app, allowing you to monitor battery metrics and diagnostics. Simply scan the QR code or search for the battery via the free app to get live information.
