Tough Power Solutions: Find the Perfect Under Chassis Battery Box

Our under chassis battery box lithium batteries are the perfect solution for serious off-roaders who need reliable power while saving internal space, along with easy compliance with Australian battery installation laws. These batteries are designed to fit seamlessly beneath your vehicle, freeing up valuable interior storage for other equipment. Built for offroad use, they deliver high-performance energy storage while maintaining structural integrity.

Whether you are looking for a caravan chassis mounted battery box, or a chassis mount battery box for your 4WD, our chassis mount designs deliver maximum durability and performance.

 

Why Choose a Caravan Chassis Battery Box for Off-Grid Adventures

At the heart of our design is a commitment to outdoor durability and ease of installation. Each caravan chassis battery box in our collection is IP67-rated, meaning it’s fully dustproof and water-resistant — perfect for tackling muddy tracks, corrugated roads, or coastal conditions. Built to handle Australia’s toughest environments, these battery boxes integrate seamlessly into your chassis without compromising ground clearance.

 

Fast-Charging, Long-Cycle Performance

When you’re off grid, having a battery that charges quickly and performs seamlessly is crucial. Our caravan underbody battery box systems offer fast charging capabilities for large solar arrays, or to take advantage of short term access to AC power when heading through town.

Thanks to our exclusive advanced Battery Management System (BMS), these batteries maintain optimal cell balance and protect against temperature, voltage, and current extremes, ensuring consistent performance over thousands of charge cycles. So, whether you're powering your fridge, lights, or other gear, you can rely on these batteries for long-lasting energy.

 

Built for Harsh Conditions

Every chassis mount battery box is constructed to withstand punishing terrain. From red outback dust to river crossings, the IP67 rating ensures your power stays protected. These battery boxes are ideal for caravans, camper trailers, 4WDs, and heavy duty trucks where reliability is critical.
