Using engine power to charge your service battery, the Orion XS DC-DC charger combines impressive power with an ultra-compact, fanless design. Available as a 12V or 12V/24V/mixed-voltage model, it's ideal for dual-battery setups and doubles as a DC-to-DC converter for sensitive electronics.
The Orion XS supports any alternator and battery setup with configurable voltage and current, achieving 98.5% efficiency and maintaining full rated output even at 40°C/104°F. It draws a stable load from smart Euro 5/6 alternators, preventing the service battery from being undercharged. The 4-stage charging algorithm adapts to discharge depth, extending battery life across all common chemistries.
Bought this to replace another brand's DC-to-DC charger which failed to charge my Auxillary Lithium Battery in my vehicle correctly. As per all of Victron's products it works perfectly. The device is fully configurable using the app. The footprint is way smaller than the Orion TR devices and it remains cool while charging.
Unlike most controllers, you can vary not just the startup pressure (which is what most other units do), but also the ongoing, running pressure output.
The controller is also much smarter than most of the slightly cheaper ones- it doesn't just give up for 24 hours if it gets no flow,for example, as some others do. For an extra 10% or 20% on the price, it's well worth the money to get a
much smarter product, that's clearly had a lot of thought go into the software.
The instructions, translated from Italian, are not the clearest, though.
