VoltX 12V 300Ah Pro Lithium Ion Battery

VoltX 12V 300Ah Pro Lithium Ion Battery (LiFePO₄)

Designed for serious power users who demand maximum capacity, extreme reliability, and professional-grade performance, the VoltX 12V 300Ah Pro Lithium Ion Battery is a powerhouse solution for large off-grid systems, high-draw inverters, and extended touring setups.

Unmatched Power & Capacity

With 300Ah of usable energy, this battery is engineered to run multiple appliances simultaneously: fridges, induction cooktops, air compressors, lighting, and inverters—without voltage sag or performance drop.

The 600A peak discharge (5 seconds) allows it to comfortably handle large inverters and sudden high-current demands, making it ideal for caravan air conditioning, heavy tools, and off-grid home systems.

Pro-Grade Lithium Performance

Lithium Iron Phosphate (LiFePO₄) Chemistry
Renowned for its superior safety, thermal stability, and efficiency, LiFePO₄ chemistry delivers consistent voltage output, faster charging, and longer lifespan compared to traditional batteries.

Prismatic Cell Construction
High-quality prismatic cells offer improved durability, balanced energy delivery, and enhanced safety under heavy loads.

Up to 4000 Life Cycles
Designed for long-term use, this battery can deliver thousands of charge and discharge cycles—significantly reducing replacement costs over time.

Built for Harsh Environments

Whether you’re touring remote locations or powering an off-grid setup, the VoltX 300Ah Pro Battery performs reliably across extreme conditions:

• Charging Temperature: 0°C to 45°C
• Discharge Temperature: -25°C to 65°C

This makes it suitable for Australian summers, alpine cold, and demanding outdoor environments.

Compact Power, Lightweight Advantage

Despite its massive capacity, this battery weighs only 27.4kg, offering a huge weight saving compared to equivalent AGM or lead-acid systems. Its compact form factor allows for flexible installation in caravans, boats, canopies, and battery compartments.
