In this video I’m installing a Victron Orion-Tr Smart 12/24-15A DC to DC charger in my friend’s van. The van has a 12 volt starter battery and a 24 volt DIY lithium house battery that I installed a few years ago, so we’re using the non-isolated 12/24 version. I’ll explain why a DC to DC charger is needed when charging lithium from an alternator, how it protects your alternator from overload, and why I chose the non-isolated model for this setup.

You’ll see a walkaround of the unit, how the input and output terminals are connected, and how the small remote port can be wired to a simple on/off switch. I also talk about cable length, fuse sizing, and why I prefer calculating fuse and wire sizes myself rather than relying only on Victron’s generic tables. We go through the numbers together and I explain how is size my wires and fuses.

After wiring everything up, I connect through the VictronConnect app to set the charger to LiFePO₄ mode and adjust the input voltage lockout so the starter battery is never drained when the engine is off. I’ll show you how the engine shutdown detection works, how the charger responds when the alternator stops, and what the app can and can’t do in terms of monitoring.

Finally I demonstrate the charger in action on the bench and then give you an overview of the completed installation in the van, with the charger, fuses, and cabling laid out.
