Razor-Thin 89mm Profile (With Mounting Tray) | Massive 300A High-Output JBD BMS | Grade 304 Stainless Tray Included | Parallel Only Configuration | Australian Designed

Are you ready to unlock an unprecedented level of power without sacrificing an inch of precious space? From our base right here in Welshpool, Western Australia, we're thrilled to unveil the revolutionary SuperSlim 300 12V 304Ah LiFePO4 battery – a true game-changer designed for the most demanding adventurers and professionals. This ultra-thin form factor is specifically engineered for mounting flat against canopy walls, behind rear seats, or in tight cargo false-floors where traditional square batteries simply won't fit, reclaiming your storage area without sacrificing a single Amp-hour.

100% Usable Capacity — Power Every Last Amp

Unlike traditional AGM or lead-acid batteries that damage themselves if discharged past 50%, 12VS Lithium batteries deliver 100% usable capacity.

• Get What You Pay For: A massive 304Ah 12VS battery gives you a full 304Ah of usable power right down to the low-voltage cutoff without dropping voltage or harming the cells.
• Half the Weight, Twice the Power: Because you can use every single amp-hour, this single powerhouse effectively replaces a massive AGM bank more than double its physical size and weight, keeping your vehicle's setup incredibly compact and lightweight.

Unmatched Power Output, Revolutionary Slimline Design

The SuperSlim 300 isn't just powerful; it's a marvel of engineering. Boasting a staggering 300A continuous output, this battery is purpose-built to handle the heaviest loads, making it the perfect partner for your 3600W inverter. Power everything you could ever need simultaneously, effortlessly:

• Heavy Domestic Climate Control: Power roof-mounted or under-bunk air conditioning layouts to stay cool and comfortable even in the brutal outback heat.
• High-Draw Cooking Arrays: Seamlessly run multiple high-draw appliances like induction cookers, air fryers, and microwaves for quick, convenient meals on the go.
• Morning Brew: Enjoy your domestic camping kettle and coffee machine, no matter how remote your campsite is.
• Living Comforts & Utility: Continuous, clean 12V power for large chest/upright fridges, cooling fans, and high-draw 12V air compressors for recovery gear.
• Remote Tech & Communication: Stable, continuous power coverage for high-speed internet via Starlink Mini, plus rapid charging for laptops and camera gear.

Infinite Scalability: Parallel Ready (Not For Series Use)

Whether you need a sleek single-battery layout or are building out a massive flat-profile house bank, the Generation 1 SuperSlim 300 is designed to scale horizontally with ease.

• Parallel Only Configuration: This battery is engineered strictly for parallel configurations to expand your total runtime. Note: This unit cannot be connected in series to increase voltage.
• Unlimited Parallel Capability: Connect multiple units in parallel to expand your total amp-hour capacity and build a massive common power wall. (Important: Batteries must be fully charged and within 0.1V of each other before linking together in parallel).
• Total Versatility: The ultimate power foundation for custom 4WD canopy builds, slim marine bulkheads, and narrow caravan storage cavities where maintaining a low profile is critical.

Massive Capacity in an Unbelievably Compact Form Factor

Prepare to redefine what's possible with a 304Ah battery. The SuperSlim 300 features an ingenious low-profile design, allowing it to mount completely out of sight and maximize your functional cargo space.

• Premium Stainless Steel Tray: To make installation as seamless as possible, every SuperSlim 300 comes complete with a rugged, custom-fitted Grade 304 stainless steel mounting tray.
• Vibration Protection: The heavy-duty tray features 3mm Neoprene rubber lining for superior vibration resistance—crucial for protecting internal architectures from brutal, corrugated outback tracks.
• Real-World Operational Footprint: With the protective mounting tray installed, the total space-saving dimensions are a remarkably slim 785mm Long x 430mm High/Wide x 89mm Deep. (Bare battery dimensions without tray are 700mm L / 745mm with terminals x 400mm W x 80mm D).
