The battery question is one of the most debated topics in Australian caravan forums. Lithium wins on almost every technical measure, but the cost difference is real.
AGM Batteries: The Case For
AGM batteries have powered Australian caravans reliably for decades. They are well understood, widely available, cheaper upfront and work with all existing charging systems. A quality 100Ah AGM battery costs $180-250 and will last 3-5 years with proper use.
Lithium LiFePO4: The Case For
- Usable capacity: 80-90% of rated capacity vs 50% for AGM
- Weight: 60-70% lighter than equivalent AGM capacity
- Lifespan: 2,000-4,000 cycles vs 300-500 for AGM
- Charge rate: Accepts much higher charge currents for faster charging
The Real Cost Comparison
A 100Ah lithium battery costs $800-1,200 compared to $200-250 for equivalent AGM. Over 10 years of regular camping, lithium typically provides lower total cost of ownership.
