Frequently Asked Questions
- Why do I need a DC-DC charger instead of a battery isolator? Modern vehicles with Euro 5/6 smart alternators don't provide consistent high voltage needed to fully charge auxiliary batteries.
- Will this work with lithium (LiFePO4) batteries? Absolutely! The Orion XS includes dedicated lithium charging profiles and critical low-temperature shutdown protection that prevents charging lithium batteries below freezing (which causes permanent damage).
- How does it protect my alternator from being overloaded? The configurable output current (1-50A adjustable) allows you to limit the charge current to match your alternator's capacity.
- Can I monitor and control it from my phone? Yes! The built-in Bluetooth Smart connects to the free VictronConnect App (iOS and Android) for complete remote monitoring and control.
- Will it charge my house battery when the engine is off? No – and that's a good thing! The engine running detection automatically disconnects your house battery when the engine stops, preventing it from draining your starter battery.
