Deep Cycle Batteries
Reliable 12V, 24V, and 48V deep cycle batteries for caravans, marine, and off-grid power systems
Reliable Deep Cycle Batteries for Off-Grid Energy Storage
Building a dependable off-grid power system starts with the right energy storage. Whether you are outfitting a caravan for long-term touring, wiring a marine vessel, or setting up a tiny home, our comprehensive range of deep cycle batteries delivers consistent power when you need it most. We offer cutting-edge lithium (LiFePO4) models alongside ultra durable AGM and gel options, catering to diverse capacity requirements from compact 12V power stations to heavy-duty 48V battery banks.
Choosing the Right Battery Chemistry
Selecting the correct battery type is critical for maximising lifespan and performance in off-grid environments:
- Lithium (LiFePO4): Offering exceptional energy density, faster charging, and a significantly longer cycle life, lithium batteries are the premium choice for modern off-grid systems. Top-tier brands like Exotronic provide smart Bluetooth connectivity and IP67 waterproof ratings, ensuring robust performance in demanding 4WD and marine setups. We also stock renowned Victron, Enerdrive, and Invicta lithium batteries, including highly sought-after 300Ah lithium battery configurations designed for extended off-grid stays.
- AGM & Gel: For smaller capacity needs or budget-conscious builds, AGM and gel deep cycle batteries remain highly effective. They are spill-proof, maintenance-free, and perform reliably in dual-battery setups under the bonnet or inside a camper trailer.
Scale Your System: Voltages & Capacities
Matching your battery bank to your electrical load and charging infrastructure is vital. Our range covers everything from compact 50Ah units to massive 400Ah powerhouses.
A standard 12V battery system is perfect for running 12V fridges, lighting, and basic appliances in caravans and boats. For larger motorhomes or commercial off-grid setups running high-draw 240V appliances via an inverter, upgrading to a 24V battery or 48V lithium battery dramatically increases efficiency and reduces cable size requirements. A popular choice for serious tourers is a 300Ah battery setup, which provides ample reserve capacity to weather cloudy days without generator backup.
Complete Your Power Setup
To maximise the lifespan and safety of your investment, pair your new batteries with appropriate charging and monitoring equipment. Safely mount your power storage using rugged battery boxes, and ensure accurate state-of-charge readings with precision battery monitoring systems. When it comes to replenishing your energy, integrate high-efficiency mains chargers for shore power top-ups, or reliable DC-DC chargers to harness power directly from your vehicle's alternator while driving.
FAQ: Off-Grid Deep Cycle Batteries
What is the advantage of a 300Ah lithium battery over AGM?
A 300Ah lithium battery provides nearly twice the usable capacity of an equivalently rated AGM battery, as lithium can be safely discharged deeper without causing damage. It also charges significantly faster and weighs a fraction of the equivalent lead-acid bank, making it ideal for weight-sensitive caravans, 4WDs, and RVs that require ample power without exceeding weight limits.
Do I need a special charger for lithium batteries?
Yes. Lithium batteries require a specific charge profile to reach their full potential and avoid damaging the internal battery cell structure. You should always use lithium-compatible chargers, solar controllers, and alternators to ensure safe and efficient charging.
Are 48V battery systems better for off-grid living?
A 48V battery bank operates at a lower current for the same power output compared to a 12V system. This allows for thinner cabling, less heat generation, and greater efficiency when powering large inverters in tiny homes, heavy-duty marine vessels, industrial equipment, and trucks. This higher voltage reduces the physical size of wiring required and increases overall system stability.
