Standalone Batteries– Overland Power Storage

The Heart of Your Overland Power System

No matter how many solar panels you have or how efficient your lights are, you need a reliable "tank" to store the energy. Xtrusion’s Standalone Batteries collection is the foundation of every serious off-grid power system. We provide high-capacity, deep-cycle energy storage solutions designed to run 4x4 fridges, radios, winches, and camp gear indefinitely.

Choosing the Right Battery for Your Build

Overlanding requires power that can handle deep discharges and extreme vibration. Whether you are upgrading to modern Lithium-Ion technology for weight savings and faster charging, or relying on the cost-effectiveness of AGM (Absorbed Glass Mat) deep-cycle technology, our batteries are engineered for the rigors of life off-road.

Key Features of Our Standalone Batteries

• Deep Cycle Performance: Designed to be discharged and recharged repeatedly without degradation, unlike standard automotive starting batteries • Extreme Vibration Resistance: Internal reinforcement and heavy-duty casings that prevent cell failure and terminal breakage on washboard trails • High Cycle Life (Lithium): Our Lithium options offer thousands of cycles, meaning a single battery can power your build for years of continuous travel • Maintenance-Free & Safe: Sealed AGM and Lithium designs are leak-proof, spark-free, and can be mounted in any orientation—ideal for enclosed 4x4 cargo areas • Temperature Tolerance: Engineered to maintain consistent output even in freezing mountain passes or baking desert heat

Expand Your Range

Don't let a dead battery strand you in the wild. By pairing our standalone batteries with our high-efficiency solar panels and smart chargers, you can achieve true off-grid independence.
