Your solar panels will work fine, but check your solar regulator first. Most Custom Lithium batteries in Australia need a regulator with lithium or LiFePO4 charging profiles (14.4-14.6V bulk, 13.6-13.8V float). If your current regulator only does AGM or gel, you'll need to upgrade. MPPT regulators give better charging efficiency than PWM types.
Unsure which you’ve got at hand? Send us your regulator model, and we'll confirm if it'll work before buying your Custom Lithium batteries.
Calculate your daily power usage in amp-hours. Add up what each appliance draws and how long it runs.
A 100Ah Custom Lithium battery handles basic camping – fridge, lights, phone charging. Extended trips or running air conditioning? Look at 310Ah+. Massive 500-620Ah models suit full-time living or commercial setups. Factor in your solar recharge capacity too.
Absolutely! Easily connect identical Custom Lithium battery models in parallel to increase capacity. Just make sure they're the same brand, model, and age, and charge them to similar levels before connecting. Each battery's BMS manages its own cells, so parallel connections work smoothly. Series connections (for 24V systems) also work, but need proper planning.
Custom Lithium batteries weigh roughly half what equivalent lead-acid batteries weigh. A 200Ah unit weighs around 25-30kg, while a 200Ah AGM weighs 55-60kg. Our larger 620Ah Custom Lithium batteries online are still lighter than comparable lead-acid banks – handy for payload limits in caravans and 4WDs.
A quality Custom Lithium battery delivers 3,000-5,000+ charge cycles depending on how you use it. If you're a regular camper heading out monthly, you're looking at 10-15 years of service. Full-time travellers cycling their batteries daily might see 8-10 years.
Proper charging, avoiding extreme temperatures, and not constantly hammering them to 0% all extend lifespan.
Custom Lithium batteries operate between -20°C and 60°C, though charging performance drops below freezing to protect the cells. You can still discharge and use your battery in cold weather – it just won't accept charge until it warms up.
They’re built for Aussie conditions, handling outback heat, tropical humidity, and cooler southern climates beautifully. Just keep them out of direct scorching sun when possible.
