Caravan Battery Systems

Caravan Battery Systems Built for Bigger Adventures

When you’re travelling with all the comforts of home, you need serious power that can keep up. iTechworld’s caravan battery systems are purpose-built for setups that need that little extra oomph, powering everything from air-cons and induction cooktops to lighting, fridges, and fans.

Designed, engineered, and tested right here in Australia, our lithium caravan batteries are built to handle long trips, harsh roads, and power-hungry appliances. Whether it’s rain or shine, these portable power solutions won’t let you down. Go free camping off-grid for weeks, or tour across the country with the help of our 4WD system. Whatever your travel plans look like, power them with our help.  

Power You Can Count On, Wherever You Go

  • High-Capacity Power: Built for power-hungry setups in caravans, camper trailers, and RVs, for fridges to CPAPs and everything in between. 

  • We Keep it Simple: Here you don’t have to piece together multiple components. Our complete caravan 12V systems combine DCDC charging, AC charging, fusing, and isolation into one neat and tidy install. 

  • Lithium That Lasts: Using premium LiFePO₄ cells, our caravan batteries are all about long lasting, usable power to take you where you need to go. 

  • Solar-Ready Systems: Connect yours with a solar blanket or panel; the perfect solution if you’re running off the grid solar systems.

  • Safe and Smart: A built-in Battery Management System (BMS) protects from over-voltage, thermal spikes, and deep discharges; even when the Aussie heat gets too much.

  • Designed for Aussie Roads: Compact, vibration-resistant housings are great for under-bed, rear compartments, or external hatches. Not only this, but they’ll protect from red dust, salt air and any bumps along the way.

  • Real Local Support: Our Aussie-based team knows caravan battery systems back to front and they’re just a call away when you need help or advice.

FAQs

What types of batteries are suitable for caravans, and how do they differ?

Lithium (LiFePO₄) and AGM deep cycle batteries are most common. Lithium delivers more usable power, is lighter, charges faster, and lasts longer; all of which make it a solid fit for heavy-use caravan setups. AGM is cheaper but bulkier and less efficient.

How long can I expect my caravan battery to last under regular use?

Lithium batteries can last 8–10 years with proper charging and use, whereas an AGM battery tends to last 3–5 years. Heat, over-discharge, and poor charging will all have an effect on the battery life.

What maintenance practices are recommended to extend the life of my caravan battery?

For lithium: monitor charge levels and avoid complete discharge. For AGM: check water levels (if required), clean terminals, and avoid letting the battery sit flat. Use a smart charger suited to your battery type.

How do AGM and lithium batteries compare for caravan applications?

Lithium wins on nearly every front: more energy, faster charging, less weight, and a longer life. However, if you’re looking for something more affordable than AGM is a solid option.

What are the recommended methods for charging caravan batteries while on the road?

Use a DCDC charger while driving, a solar blanket when parked, and an AC charger when connected to mains. The best caravan battery systems use all three to stay topped up no matter where you camp.

Is it necessary to install lithium batteries in a ventilated area within my caravan?

No, iTechworld lithium batteries are sealed and safe to install inside your van. Just ensure adequate airflow around any connected inverters or chargers.

Can I integrate solar panels into my caravan's electrical system for battery charging?

Yes. A solar-ready DCDC charger or solar controller makes it easy to connect portable or fixed panels - great for staying off-grid without running the car.

What is an auxiliary battery, and why is it important for caravan use?

It’s the auxiliary battery that powers all your 12V appliances such as your fridge, lights, and pump. This doesn’t drain your starter battery, making it a must-have for any caravan setup.

How do I determine the appropriate battery capacity for my caravan's energy needs?

Calculate how many amp-hours (Ah) your appliances use daily, then add about 20% buffer for safety. A 200Ah lithium setup is common for caravans running fridges, fans, and devices, but larger setups may need 300Ah or more.

What safety precautions should I take when installing or replacing a caravan battery?

Use proper fuses, follow cable size recommendations, secure everything tightly, and always disconnect power before working. iTechworld always recommends a professional install for more complex systems.

Are there specific chargers recommended for different types of caravan batteries?

Yes. Use a lithium-compatible charger for lithium batteries, and an AGM-compatible one for AGM. iTechworld AC and DCDC chargers auto-detect chemistry and apply the right charging profile.

How does temperature affect the performance and charging of caravan batteries?

Extreme cold can slow lithium charging; extreme heat can reduce life. All the lithium batteries you find at iTechworld have built-in thermal protection so they can handle any condition that comes their way.

What are the signs that indicate my caravan battery needs replacement?

Short runtime, slow charging, swelling (for some AGM models), and voltage drop under small loads. Use a battery monitor for early warning signs.

Can I use my caravan battery to power household appliances during off-grid camping?

Yes, with a quality pure sine wave inverter. You’ll be able to run microwaves, kettles, TVs, even air fryers. All you have to do is match your battery capacity and inverter size to the appliance draw.

What is the role of a battery management system (BMS) in caravan setups?

The BMS manages and protects the battery to prevent overcharging, deep discharges, and short circuits. It’s what makes lithium batteries safe and long-lasting.
