Battery Charger FAQs

What does a DC to DC battery charger do?
A DC to DC battery charger takes power from your vehicle’s alternator and safely converts it into the correct voltage and current to charge your caravan’s auxiliary battery. This ensures lithium, AGM, or gel batteries are charged efficiently and safely without overloading the system.
Is a DC to DC charger worth it?
Yes. Unlike a standard 12V battery charger or alternator connection, a DC/DC charger delivers a controlled, stable charge that improves battery health and performance. It’s especially important for lithium batteries in caravans, which need a precise charging profile.
Do DC to DC chargers drain the main battery?
No. A DC to DC charger is designed to prioritise your vehicle’s starter battery. Once the engine is off, it stops drawing power, ensuring you’re never left with a flat starting battery.
What are the disadvantages of DC to DC converters?
The main disadvantage is cost compared to a basic battery isolator. However, the benefits — safer charging, higher efficiency, and compatibility with lithium batteries — far outweigh this for most caravan owners.
What is the disadvantage of DC charging?
DC charging requires the engine running or an active power source, so it won’t top up your battery unless your alternator or solar is feeding power. For long stays without driving, you’ll still need solar panels or a mains charger.
What size DC to DC charger for a 100Ah lithium battery?
For a 100Ah lithium caravan battery, a DC to DC charger rated between 20A and 40A is typically recommended. The DCX 850W DC to DC charger provides high-output charging suitable for larger systems, including 48V setups, offering rapid and safe replenishment on the move.
