High-Capacity Batteries Built for High-Demand Power Systems

If you're operating high-draw appliances like large inverters, induction cooktops, air compressors, or multi-day setups without solar input, you need more than a typical 100Ah - 200Ah system. A 300Ah lithium battery gives you the ability to run more gear for longer, without compromising reliability or risking deep discharge damage.

LiFePO4 technology guarantees consistent output, superior safety, and faster recharge times. Whether you're running a full off-grid caravan, a work ute with heavy electrical loads, or a 4WD with complex dual battery systems, this range of large lithium batteries provides the kind of dependable, long-lasting energy storage that lets you go further and stay out longer.

Practical Solutions for Touring, Work, and Remote Power

The 300Ah lithium battery is ideal for more complex power systems, particularly where redundancy and longer off-grid autonomy are required. It’s well suited for when you’re running high-draw appliances, larger inverters, or extensive 12V networks. If you want peace of mind over extended periods when you’re away from mains power, a 300-amp lithium battery will serve you well.

Slimline, Bluetooth, and Chassis Mount Options

You’ll find more than just capacity in our range - you’ll also find the right format to match your installation requirements. Our slimline lithium battery 300Ah model offers a flat-profile design ideal for under-bunk, false floor, or behind-seat setups, giving you serious capacity without sacrificing space.

Our Bluetooth-enabled lithium batteries make system monitoring effortless. Check voltage, charge levels, and temperature directly from your smartphone - no additional hardware required. It’s an excellent feature for ensuring your battery stays healthy and performing at its best.

For even tougher builds, the chassis-mounted batteries in our range come IP67-rated for dust and water resistance, with hard-wearing enclosures designed for harsh Australian conditions. These include 200Ah, 300Ah, and 400Ah lithium battery models - perfect for under-tray, under-vehicle, or exposed installs where durability is critical.
