150Ah HP Slimline Lithium Battery is constructed using the latest lithium ion phosphate cells. These prismatic cells are of the highest quality in a metal hard case. The battery has an inbuilt Battery Management System (BMS).

At just 18kg, the unique slimline shape makes it the perfect battery for installations where space is a premium. Slide it behind a seat, bolt it to a wall or at the back of a cupboard.

The Slimline 150Ah battery provides up to 200A of continuous discharge or charge and can be stacked in parallel to increase amp hour storage capacity. Charge and discharge are via the four grey Anderson plugs.

The strong aluminium outer enclosure delivers a safe, lightweight, and powerful unit which is perfect for 4WD and Camper Trailer installs.

150Ah HP Slimline Lithium Battery flows up to 200A, capable of running up to a 2000 watt inverter, alternatively parallel two batteries for the ability to run a larger inverter.

Why our lithium batteries are superior to others in the market:

  • Massive 5 Year Warranty
  • Designed and assembled in Australia
  • Custom designed 200A BMS (Battery Management System) by engineers in Brisbane
  • Constructed using latest lithium iron phosphate cells
  • Local after-sales support

Why Lithium?

Lithium batteries provide more usable capacity than lead acid batteries. Deep discharging does not affect the life of a lithium battery the way it does with lead acid batteries. You can use the battery longer before needing to recharge, without damage to the battery.

Cost Effective Over Life Cycle

When considering the usable capacity and lifespan of lithium batteries, they work out cheaper than lead acid. When you add the cost and inconvenience of refitting new lead-based batteries every few years the total cost of ownership over the long term is far better with lithium batteries.

Longer life

Lithium batteries are rated for 2,000 – 5,000 cycles and much more if used carefully, giving you several times the life expectancy of standard lead acid batteries.


Lithium batteries allow you to pull far more amps out of the same size battery systems.


Lithium batteries are less than half the weight of the equivalent lead acid battery. Lithium batteries can be up to a third of the weight of the equivalent lead acid AGM battery. This is an important consideration for anybody who is mobile.

A 100Ah AGM deep cycle battery can be up to 38kg in weight, whereas the same size lithium battery can be less than 12kg in weight!

That means you can at least double or even triple the stored battery capacity on a RV, or alternatively use the reduction in battery weight to bring more water, or food or luggage on your trip.

Reducing weight in a RV helps to keep you under the tare weight, reduces aerodynamic drag which improves fuel efficiency while on the road.

Lighten your load with lithium!
Fast recharge

Lithium batteries charge more efficiently, and don’t require as many stages during charging. Therefore, they will charge faster, and hold more of the energy from solar panels and other charging device.


Can I charge via solar?

Yes, you can charge via regulated solar, using the Grey Anderson input.

What can I run from the Grey Anderson plug?

The Grey Anderson plugs are both in/out, you can charge and run loads, such as fridges, lights, and 12volt accessories.

How do I monitor my Slimline battery?

Via the Victron Smart Shunt Battery Monitor.
