A DC-DC battery charger also known as battery to battery charger, utilises your vehicles alternators to charge your Lithium batteries. Most vehicles have plenty of spare capacity in the alternator to divert DC current to other parts of the vehicle. The DC-DC charger unit will use the spare power supplied by the alternator and boost the voltage to a safe level for charging your lithium battery efficiently. This will preserve the life of the Lithium Battery. It will regulate the amount of current used to being drawn from your alternator to charge the lithium leisure battery.
Victron’s Orion-Tr Smart 12/12-30A non-isolated DC-DC charger is Victron’s professional solution for charging a 12V auxiliary or leisure battery from your engine’s 12V alternator. It is fully compatible with ‘smart’ alternators found in Euro 5 and later vehicles and is Bluetooth-enabled, so can be monitored and configured remotely via the VictronConnect app. It can be used to charge all lead-acid battery types (wet, Gel, AGM) as well as lithium. The charging profile is fully configurable to allow you to match the voltages recommended for battery.

Pre assembled Orion XS 50A DC-DC-Battery Charger KIT Engineered from the ground up, the Orion XS is Victron Energy's highly anticipated next generation DC-DC charger that redefines charging on the move for dual battery systems with a smart alternator. With huge improvements over the previous Orion-Tr Smart DC-DC charger, this device not only ensures the latest in battery charging performance, but its host of protection features also guarantees the safety of your system. The output charge current can be set by the user and innovative cooling technology provides a 98% efficiency without the need for a fan or heatsink, enabling a lightweight and compact, but powerful charging unit. Victron's adaptive 4-stage charging algorithm alters the absorption time to suit the depth of discharge to prevent over-charging, and the user can select from 8 pre-programmed charging algorithms or create a fully customisable algorithm to match the battery manufacturer's charging requirements The Orion XS is IP65 protected and will produce the full rated output of 50A up to
See below for a full description of improvements over the Orion-Tr Smart DC-DC chargers: Increased power with user-selectable charge current The Orion XS can deliver 50A of charge current (700W), providing faster charging and making better use of more powerful modern alternators. But the real innovation here is that Victron has provided the ability for the user to set the charge current to meet their requirements (in increments of 0.1A). This is a huge advantage for users wanting to future-proof their charging system if, for example, they one-day plan to add a second battery in parallel, change to a lithium battery (that can accept a higher charge current) or upgrade their alternator. They can run the charger at a lower output initially, and release its full potential later on. Higher efficiency with much lower heat generation One of the issues with the Orion-Tr Smart DC-DC chargers was that they generated a lot of heat. Victron has re-designed the electronics in the Orion XS to use an
The Orion Smart unit can operate as a fully configurable battery charger with an adaptive 3-stage charging algorithm, or as a DC-DC converter.
Unlike other DC-DC chargers that rely on hard-wired signalling from the alternator or ignition, the Orion Smart does not require any additional wires or sensors which simplifies installation. The ‘engine-on’ detection is software-driven and is fully configurable via the VictronConnect app.
