Frequently Asked Questions About Custom Lithium Batteries

Do you sell Custom Lithium dual battery systems?

Yes. The Custom Lithium dual battery systems on this page are shaped for a specific vehicle, so they go in without a tray or extra fabrication.

  • Ford Ranger dual battery: 100Ah or 200Ah, no drill, for dual cabs from 2015 to 2026 (PX2, PX3 and Next Gen RA). The Super Duty dual cab is an easy fit.
  • Ford Everest dual battery: 100Ah under the floor on Next Gen 2022 and later models, including the Premium Audio Pack, and you keep the jack and tool holder.
  • Isuzu MU-X dual battery: 100Ah under the rear floor on 2022 and later models. A second unit can sit beside it for 200Ah, still under the floor.
  • LandCruiser 79 Series dual battery: 200Ah or 230Ah behind the seats. Dual cab only, facelift and pre-facelift.

If your vehicle is not on that list, ring us on 1300 902 361 and we will check whether a standard Custom Lithium battery is the better fit.

Can I charge Custom Lithium batteries with my existing solar setup?

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.

How do I know which capacity Custom Lithium battery for sale suits my needs?

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.

Can I connect multiple Custom Lithium batteries together for more capacity?

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.

How heavy are Custom Lithium batteries compared to lead-acid?

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.

How long does a Custom Lithium battery last?

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.

What temperature range can Custom Lithium batteries handle?

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.
