The Victron Energy Orion-Tr DC to DC Converter 12/12-Volt 9 amp 110-watt (isolated) steps up or stabilizes 12V power for dual battery systems, ideal for van, boat, and vehicle owners who need galvanic isolation between batteries. Order online now at the current price of $36.50, down from $73.00, and apply coupon OUTPOST12 for an additional 12% off.
Choose the isolated model when you must prevent ground-loop interference, protect sensitive electronics, or separate house and starting battery grounds. Non-isolated models are cheaper but share a common negative — the isolated Orion-Tr is the right pick for marine radios, RV house batteries, and noise-sensitive loads.
The Orion-Tr 12/12-9 is a power supply/converter, not a multi-stage charger, but its adjustable output lets it float charge a 12V battery when set to the correct voltage. For full multi-stage charging, pair with a Victron charger or choose an Orion-Tr Smart model.
$36.50 vs $73.00 saves you $36.50 — and the extra 12% coupon makes it even more affordable. Free shipping on orders over $45.00.
Isolated 12V/12V 9A 110W output for safe dual battery charging and noise-free power — half price at $36.50
IP43 splash-resistant protection and easy screw-terminal installation for vehicles, boats, and off-grid rigs

The Victron Energy Orion-Tr isolated DC-DC converter delivers 9A / 110W of regulated 12V power with high efficiency and IP43 splash resistance. At $36.50 (save $36.50), it is the affordable way to power a second battery safely.
Order online for $36.50, apply coupon OUTPOST12 for 12% more off, and enjoy free shipping over $45.00.
Choose isolated when you need galvanic separation between battery negatives — for marine electronics, ground-loop prevention, or protecting sensitive loads. Non-isolated suits simple shared-negative setups.
It is a DC-DC converter/power supply, not a multi-stage charger, but it can float charge a 12V battery when its output is set to the proper float voltage.
The current online price is $36.50 versus a $73.00 compare-at price — a 50% discount — plus an extra 12% off with coupon OUTPOST12.

Isolated models keep input and output circuits electrically separate; non-isolated models share a common negative. Isolated units cost slightly more but protect against ground loops.
Keeps my trailer's battery float-charged from the tow vehicle with full isolation so the starting battery never drains. Zero voltage sag issues, runs cool, and the IP43 rating gives me confidence in wet weather. Victron quality is consistent as always.
Charges my secondary battery as expected. It does get warm under sustained load, so mount it somewhere with airflow. Efficiency seems right around spec based on my shunt readings.
No fan noise, no radio interference, steady output. Exactly what I needed for my ham radio power setup.
The unit itself is fine, but I initially undersized my input wiring and it tripped into fault mode a few times. Once I ran proper gauge cable it's been rock solid. Read the install manual carefully — wiring matters with these.
I specifically chose the isolated version because of noise-sensitive equipment in my truck camper. Ground loop problems I had with a cheap isolated converter disappeared completely. Output is clean and stable even when the engine is idling.
Installed to charge my house battery from the outboard's charging circuit. Handles the load without breaking a sweat and the VictronConnect config let me set the exact float voltage my lithium bank wants.
Compact size made mounting under my seat easy. Configurable through VictronConnect with the cable — a nice bonus. Nine amps is enough for maintenance charging but don't expect it to quickly recharge a depleted big battery.
My fault for buying 9 amps for a 200Ah battery bank — it just takes forever to charge. The unit works fine itself but I should have bought the 30A model. Leaving a middle-negative review for anyone sizing their converter.
Replaced my old voltage-sensitive relay with this and never looked back. True isolation, no voltage drop complaints, and my starting battery stays full. The adjustable output via VictronConnect is a huge plus for lithium.
Two years in (bought one at full price, this is my second unit) and the first has never missed a beat. Bought this one for the boat. Installation is straightforward if you can crimp and follow a diagram.
