  • High 50 Amp Output With Adjustable Current Control: Set charge current from 1 amp to 50 amps to match system limits.
  • Fanless High-Efficiency Operation at 98.5 Percent: Maintains output in tight spaces without noise or active cooling.
  • Adaptive 4-Stage Smart Charging Algorithm: Adjusts charging behavior based on battery discharge depth.
  • Smart Alternator Compatibility With Stable Input Draw: Prevents cycling and undercharging on variable voltage systems.
  • Sealed IP65 Design for Harsh Install Locations: Dust-tight and protected against heavy rain in exposed environments.

Features to know about

Delivers Controlled Alternator Charging for Lithium Systems

Factory alternator feeds often leave lithium batteries partially charged or cycle unpredictably with modern smart alternators. This unit regulates input from 9V to 17V and delivers controlled output with adjustable voltage and current from 1 amp to 50 amps. Batteries charge consistently while driving instead of sitting below full capacity.

High Efficiency Fanless Operation in Tight Installations

Many DC-DC chargers rely on fans and lose output in confined spaces due to heat buildup. This unit operates at 98.5 percent efficiency with a fanless design, maintaining full output in enclosed or high-temperature locations. Charging stays consistent without added noise or thermal throttling.

Adaptive 4-Stage Charging Matches Battery Conditions

Simple charging setups fail to adjust for battery state, leading to incomplete charging or long-term battery stress. The adaptive 4-stage algorithm adjusts charging behavior based on shallow or deep discharge. Batteries reach proper charge levels and maintain better long-term performance.

Smart Alternator Compatibility Prevents Charge Cycling

Variable voltage alternators can cause chargers to cycle on and off or reduce charging effectiveness. This unit maintains a stable input current draw with engine running detection, ensuring consistent operation with Euro 5 and Euro 6 alternators. Charging continues instead of dropping out during voltage fluctuations.

Configurable and Expandable for System Growth

Fixed-output chargers limit flexibility when battery systems or load demands change. This unit allows voltage and current adjustment and supports parallel operation to increase total output. You can tune performance now and expand capacity later without replacing the charger.

The converter is awesome. The engine shut down detection works perfectly on my Sprinter. My battery stays charged up and is easily verified by the app.

These are a great addition to your Off Grid electrical system. We design and install systems with them all the time at Atlanta RV Center along with other Victron components like Multiplus inverters. With professional design and installation this will keep your batteries charged while driving between stops on your adventure.

Orion XS works flawlessly. Charges 300AH lithium battery quickly and efficiently while driving. Note that etrailer Q&A says you need to run ground from negative battery post as well as to chassis ground per wiring diagram. I got contrary advice from RV wiring specialists and this additional chassis ground is not required.

  • Which DC to DC Converter for Converting Motorhomes House Batteries to Lithium
    Hey Henry for a typical lithium conversion on your 2022 Winnebago Adventurer, I recommend the Victron Orion XS 12/12-50A DC-to-DC Charger, part # VN93VR that you referenced. This charger will limit the amount of current pulled from the chassis charging system to 50 amps, helping protect the alternator while providing the proper charging profile for LiFePO4 house batteries. Victron recommends installing a 60- to 70-amp fuse on both sides of the charger. One fuse near the chassis start battery...

  • Can Vehicle 7-Way Charge Batteries for Trailer Winch
    Hey Paul! You can connect the batteries to the 7-way on your truck. However, the 12V from the factory 7-way is really designed to be a maintenance charge. Between the smaller gauge factory wiring and the long run from the alternator to the back of the truck, the voltage drop is significant. Because of that, it typically won’t put enough current back into the batteries to recover them after using a winch. If you're actually running your batteries down with the winch, a DC-DC charger like...

  • Does Install of Victron Orion XC RV Converter Ground to Battery and Chassis
    Hey Ken, when wiring up the Victron charger part # VN93VR you do need to run the ground from the negative battery post as well as to a chassis ground. I know that seems redundant but in every diagram in the instructions that step is shown. I attached a wiring diagram for you to check out as well.

  • Will Victron Orion XS RV Converter VN93VR Charge Chassis Battery When Connected To Shore Power?
    Hey David, thanks for reaching out. No, that Victron Orion XS RV Converter # VN93VR isn’t going to do what you’re thinking in that situation. It’s built to take power from one 12V source, usually your alternator while the engine is running, and charge another battery bank. With the engine off and plugged into shore power, there’s no DC source feeding it in the right direction, so it’s not going to charge your chassis battery. In a Class A, shore power is handled by your converter, and...

  • Availability of Victron DC/DC Battery Charger With Lithium Compatibility and Engine On Detection
    Hey Lee! The Victron parts can get pretty confusing. The Victron Orion-Tr # VN75ZR is only designed to be a power supply for DC loads, not for battery charging. You do not want to use this converter to charge any type of battery. To charge your batteries you can use one of the following: -Victron Orion-Tr Smart DC/DC Isolated RV Converter - 24 Volt/12 Volt - 20 Amps # VN32ZR -Victron Orion XS DC/DC RV Converter - 12 Volt/12 Volt - 50 Amps # VN93VR The main difference between the two...

  • Parts Needed for Installation of Victron Orion XS DC/DC RV Converter
    Hey Stacey! To install the Victron Orion XS DC/DC RV Converter # VN93VR you will need appropriately sized wire and fuses. Victron recommends 16 mm² / 6 AWG (13.3 mm²) cable if the distance is less than 5 meters, and 4 AWG (21.2 mm²) if it is 5-10 meters. They also recommend two 60-70A fuses, one on the input and one on the output side of the charger. See the attached photos. The installation time will vary depending on the exact setup and if you're adding anything else like the SmartShunt...

  • DC to DC Charger for 2023 Ford F-350 Towing Brinkley G3500
    Hey Keith, nice 5th wheel! We do have what you need to get power from your vehicle to the Brinkley. The Victron Orion XS # VN93VR is what I recommend. This DC to DC charger will allow you to safely charge your batteries with your 2023 F-350 alternator. It features engine shutdown detection so it will only pull power when the truck is running. It also has a 50A output so you will get meaningful charging on what I'm sure is a 200-300 Ah battery bank. The Orion XS is lithium compatible and...

  • Which Victron Orion XS DC To DC Charger Is Best For Silverado 2500 Charging 200 Ah Battery Bank
    Hey AJ! The best option for your setup is the Victron Orion XS RV Converter - DC to DC - 12V/12V - 50 Amp # VN93VR. This will take power from your truck’s alternator and charge your RV batteries while also preventing any backfeeding into the truck. The 50A output is a great match for your 200Ah battery bank, so you'll get solid charging while you're driving. The other model you were looking at is designed for higher voltage systems, which you don't need for your specific setup. What...

  • Charging Components for RV With 2 300Ah Lithium Chassis Batteries
    Hey Gerritt! You're thinking along the right lines. With a 120A alternator and a 600Ah lithium house battery bank, I recommend using a DC-to-DC charger like the Victron Orion XS 12/12-50A DC-DC Charger # VN93VR. The charger limits the amount of current the lithium batteries can draw from the alternator, while also providing the proper charging profile. That's a much better solution than a standard battery isolator, which simply connects the batteries together and doesn't limit charging...

  • Best Victron Orion DC-to-DC Charger for a 2018 Silverado and 2026 E-Pro 19FD
    Hey Kevin, thanks for reaching out. For your setup, go with the Victron Orion XS RV Converter -50A # VN93VR. With a 314Ah LiFePO4 battery, a 50-amp charger is a good match and will make much better use of your drive time than a 30-amp unit. Your Silverado has the charging system to support it, and with a battery that size, the extra charging current is definitely worthwhile. I also recommend the non-isolated version. Since your truck and trailer already share a common ground through the...
