The Bluetooth app works perfectly. - This product works exactly as described. It’s a regulated DC/DC power supply and a DC charger. I’m using it to charge a 100A LiFePO4 battery in my vehicle to run a ham radio 100W transceiver. You can use the Victron app to choose a Lithium battery so no custom programming is needed. It’s isolated from the car battery so no issue of discharging your car battery. It also eliminates some of the RF noise from the alternator. Review: Great Solution for Charging Auxiliary Batteries Without Draining the Starting Batteries - I bought this Victron Orion-Tr Smart DC-to-DC charger to charge auxiliary batteries I was installing on my truck. I specifically did not want the auxiliary batteries directly connected to my starting batteries, for obvious reasons, and this charger did exactly what I needed. It’s not the highest-output charger available, but for my application the 18 amps is enough, and it charges my auxiliary batteries just fine. The built-in engine shutdown detection is especially useful because it can detect when the engine is running by monitoring the voltage coming from the starting battery and alternator. When the engine is running and the alternator raises the voltage, the charger can charge the auxiliary batteries, and when the engine shuts down, it stops charging so it doesn’t drain the starting batteries. Victron is a brand I’ve had very good experience with, and the Bluetooth connection to the VictronConnect app makes it easy to configure the charger and monitor what’s going on in real time. For my purposes, this was exactly the right solution: reliable, isolated charging for my auxiliary battery bank without risking my truck’s starting batteries. Five stars. ## Features - PROFESSIONAL DC TO DC CHARGER: The Orion-Tr Smart DC-DC Charger is a professional charger that uses three stages to efficiently and safely charge your batteries. - DUAL BATTERY CHARGING: The Victron DC to DC charger is ideal for vehicles or boats where the alternator and start battery are used to charge the service battery. - BUILT-IN BLUETOOTH: The DC to DC charger can be monitored and cotrolled with smartphone or tablet via Bluetooth and the VictronConnect App. This allows you to see the charger's status and make adjustments as needed. - FLEXIBLE POWER SOLUTION: The DC DC charger is suitable for both lead acid and lithium batteries and unlimited multiple units can be connected in parallel to increase output power. - EASY TO INSTALL: The screw terminals provide a convenient and easy installation process, eliminating the need for specialized tools. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0851TPKV7 | | Amperage | 18 Amps | | Battery Charge Time | 1 Hours | | Best Sellers Rank | #22,291 in Automotive ( See Top 100 in Automotive ) #121 in Battery Chargers | | Brand | Victron Energy | | Built-In Media | Victron Energy Orion-Tr Smart 12/12-Volt 18 amp 220-Watt DC-DC Charger Isolated (Bluetooth) | | Color | Blue | | Connector Type Used on Cable | Screw Terminals | | Current Rating | 18 Amps | | Customer Reviews | 4.6 out of 5 stars 872 Reviews | | Input Voltage | 12 Volts (DC) | | Item Dimensions D x W x H | 2.8"D x 7.3"W x 5.1"H | | Item Type Name | Victron Energy Orion-Tr Smart 12/12-Volt 18 amp 220-Watt DC-DC Charger Isolated (Bluetooth) | | Item Weight | 1.2 Kilograms | | Manufacturer | Victron Energy | | Mfr Part Number | ORI121222120 | | Model Number | ORI121222120 | | Output Voltage | 12 Volts (DC) | | Product Dimensions | 2.8"D x 7.3"W x 5.1"H | | Warranty Description | Warranty | ## Product Details - **Brand:** Victron Energy - **Color:** Blue - **Item Weight:** 1.2 Kilograms - **Output Voltage:** 12 Volts (DC) - **Product Dimensions:** 2.8"D x 7.3"W x 5.1"H ## Images ![Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) 12/12V 18A 220W | Battery Charger for Dual Battery Systems - Isolated - Image 1](https://m.media-amazon.com/images/I/71Cf-mwN0uL.jpg) ## Questions & Answers **Q: This unit has been triggering my RV's low voltage proection, likely from random spikes. Anyone have an idea on how to disable it?** A: Yes, the same thing happened to me with my 30A Victron dc-dc on my 2021 Ford Transit starter battery. The answer is to use the 18A victory dc-dc charger. I learned this the hard way. Some cars can't handle that draw. **Q: Would it harm this victron 12-12-18 if I mounted it in a pickup truck engine compartment, connectors at the bottom and air space around it?** A: For good cooling effect, the Oion is designed for vertical mounting only. Other mounting methods may impair cooling and reduce the service life of the product. **Q: Can I connect the input and output ground together?** A: Yes if not trying to isolate like in a boat for galvanic corrosion. If you don't need the isolation feature just purchase the non-isolated model and save a few dollars. If you already own the isolated model and installing in a RV you can ground both to same ground connection. **Q: I'm looking to find a dc-dc charging solution that also accepts solar input. i'd rather have victron vs redarc or ctek?** A: I use two separate devices. Solar is in series so the input ranges up to 100 volts. It’s nice seeing both via Bluetooth. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super easy way to charge a second battery in your vehicle.
