Frequently Asked Questions (FAQs)

1. What is a DC to DC charger and why do I need one in Australia?

A DC to DC charger safely charges your auxiliary battery from your vehicle’s alternator or solar panels. In Australia, where long-distance touring, remote camping, and harsh weather are common, it ensures stable, efficient charging across rugged conditions.

2. Is a DCDC charger required for dual battery setups in 4WDs or caravans?

Yes. Whether you're touring Cape York or camping along the coast, a DC-DC charger is essential for keeping your second battery charged safely and reliably  especially in modern vehicles with variable voltage alternators.

3. Do I need a DC DC charger if I’m running a lithium battery?

Absolutely. Lithium (LiFePO4) batteries require precise charging profiles. Without a DC-DC charger, you risk damaging the battery or never fully charging it.

4. Can I use a DC to DC charger with solar panels on my van or off-grid setup?

Yes. Most quality DC-DC chargers (like ours) include a built-in MPPT solar regulator, allowing seamless input from your solar panels and vehicle alternator and ideal for off-grid or hybrid systems.

5. How do I choose the right size DCDC charger  20A, 40A, or 60A?

It depends on your battery bank and how quickly you want to charge it. A 40A unit is ideal for larger battery setups or frequent power use. A 20A charger may suit small setups or weekend trips. Always check your alternator’s capacity.

6. What’s the difference between DC to DC and AC to DC battery chargers?

A DC-DC charger is powered by your vehicle (12V or 24V) or solar while you're on the move. AC-DC chargers plug into 240V mains power ideal when parked at a powered campsite or home.

7. Will a DC to DC charger prevent my starter battery from going flat?

Yes. It isolates your main battery from the auxiliary one, ensuring the engine battery is never drained when you’re running appliances off-grid.

8. Are your chargers compatible with AGM or lead-acid batteries?

Yes. Our units support multiple chemistries including AGM, Gel, Flooded, LiFePO4, and Sealed lead-acid — just set the appropriate charge profile.

9. Can I install the charger myself, or do I need an auto electrician?

If you're experienced with dual battery installs, it can be DIY. But for safety, we recommend professional installation especially in vehicles with complex electronics or smart alternators.

10. Are your DC to DC chargers legal and compliant for use in Australia?

Yes. All our chargers are compliant with Australian safety standards and tested for local conditions including dust, vibration, heat, and humidity.

11. Do your chargers work with brands like Redarc, Victron, or Enerdrive?

Yes. Our DC to DC chargers integrate seamlessly into setups featuring Redarc, Victron, Enerdrive, and other popular Australian systems.

12. Can I run my fridge or accessories directly from the charger?

The DC-DC charger charges your auxiliary battery, your fridge and accessories should be wired from that battery, not directly from the charger.

13 Do you offer support and warranty in Australia?

Yes. We provide fast shipping, real local support, and warranty coverage from within Australia. No offshore call centres, just real help when you need it.
