Orion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 18 amp 220-Watt - Battery Charger for Dual Battery Systems - Isolated

These things aren't as "smart" as some of the other Victron stuff - for example you cannot limit its max output current, but it's simple and works great. Since it cannot be limited I went with the 12/12 18A instead of the 12/12 30A to ensure I don't blow 12V aux fuses when the batteries are low. We upgraded the batteries in our Jayco 312BHOK to LiPo4 batteries and I wanted to make sure the trailer was "adapted" instead of worrying about back feeding or charging issues. I simply disconnected the Aux Charging leg of my 7 way from the trailer, ran it to the input side of the 12/12 18A, connected the - input leg to the ground coming off the 7 Way, and then ran the +/- outputs directly to my battery bus bars with a 30 amp breaker on the positive leg. It pretty much worked out of the box with one minor adjustment needed for my 2500 CTD Tow Vehicle - I had to change the Alternator detection from "Smart Alternator" to "Standard Alternator", but that was it. It detected that it was charging lithium batteries on its own and it does isolate the camper from the tow vehicle. Doing it this way I am limited to 18A of charge current from the my truck, but that's more than enough to run my 12V fridge going down the highway. We don't really do any boondocking or dry camping so I liked this solution of being able to tow it with any truck rather than using a bigger charge controller with extra dedicated high amperage 12V plugs that would limit me to only being able to charge with my truck towing it.

You probably already know that the 7 pin tow connector that is standard when towing a travel trailer is useless for charging the trailer's batteries - given the distance from the tow battery to the trailer battery you are lucky to get a trickle charge at best. So you need a DC-DC charger to do the job and I chose the 18 amp Victron to charge our 100Ah travel trailer battery. I wired in an 8 gauge hot wire from the tow vehicle's battery (a Jeep JKUR) back to the hitch and used a pair of 50amp connectors and ran a second hot wire from the hitch back to the Victron and then the battery. I ran 10 gauge black wire to the frame on both vehicles off the connectors. It all works perfectly, and I can monitor the state of charge from the tow vehicle using the Bluetooth app. You can program the voltages for each charging stage for any battery type and program an auto-shut-off so you don't drain the tow vehicle's battery if you stop the motor. All in all I'm very happy - the Jeep has a 160 amp alternator and doesn't seem to notice the load at all. Should you go big and up it from 18 amps to 30 or 40 amps? Well, if you have a big alternator and more battery capacity then yes, that would be a good idea. Of course you'll have to install big wire which costs more than my 8 gauge - I'd go 1/0 for 30 amps or more. In terms of how long it takes to recharge the battery, well it has been on float when we arrive at our next destination after a few hours driving. One time I just idled at a campsite to charge - while not as quick or fuel efficient as a generator, it will certainly get you by in a pinch and make a generator quite optional in many cases.

Works great on my boat. You can even see what it’s doing in the app without any issues at all. Victron knows what they’re doing!

Easy installation. Good isolation of vehicle starting battery and my Scamp battery so now the trailer is fully charged between camps while running the dc refrigerator and is ready for solar maintenance while in camp. Can leave truck hooked up without draining the starter battery too.

Works well so far for maintaining battery in my trailer while towing. I connected it via the 7 pin and have no issues, I doubt I’ll see the full 18 amps due to voltage loss because my wire size in the 7 pin connector is 10 gauge. From the 7 pin trailer wire harness I went to 6 gauge up to the Orion. At some point I may run a dedicated 6 gauge line from the tow vehicle battery but works fine for now.

I did return it because the vehicle wasn’t supplying the consistent voltage from my Nissan. (Alternator not supplying power 100% of the time) so my lithium wasn’t charging all the way up. Other than that, very easy to use and adjust on the app that comes with it. You can adjust settings on the fly while in the vehicle from your phone. I do recommend their products. Good quality product and well built. Paul Tretiakoff in Arizona K6PPT WRXR619

Easy to install and works correctly. Company is helpful setting the units values up correctly. Like having the peace of mind that my alternator won’t be damaged with lithium batteries. Bluetooth functions are flawless even after sitting all winter. Highly recommend!

I use this to charge a 12v LiFePO4 140ah dual mode battery (dedicated for my auto leveling jacks) from the main 12v battery bank. While the charger works good for this use case, 220W is plenty to slow charge the 140ah battery from time to time, this product and Victron really upsets me. You would assume that a Victron "Smart" charger would integrate with their CerboGX ecosystem. You would assume wrong. This is an extremely expensive 12v-12v charger that is only "smart" because you can connect to it via Bluetooth using an app. Why you can't connect it to the CerboGX via Bluetooth is beyond stupid. The CerboGX supports 3rd party devices connecting via Bluetooth. After I purchased and installed this charger, I found out that Victron customers have been complaining about this for several years. Recently Victron released the Orion XS version of dc-dc charger. The main difference is that it will connect to the CerboGX. There are two versions, one 700 watt at about $300 and the other 1400 watt. Thanks Victron, way to show that you care about your customers by rolling out an even more expensive product (that may not be useable for certain use cases) at twice the cost instead of updating the firmware on the Orion TR line and the CerboGX.

Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 18 amp 220-Watt - Battery Charger for Dual Battery Systems - Isolated Does not come with BT antenna connection. As I said long very good experience with Victron equipment, mostly battery chargers. Bought the 100V 30 amp 12/24-Volt when I started in Solar, great kit, tried all sorts of different types. Victron comes out tops. Should have stuck with Victron. This DC-DC charger is a little difficult to setup, rookie should be good with the setup as long as they check & double check. Ensure all crimps are good (Some of the crimps are poor, My 12V setup is 2 by 100 AH lead acid batteries & 2 by 130AH leisure batteries, supplied by a small mains homemade charger using a 240/15V Tx, 50A Full-wave rectifier with 2 10A Germanium blocking diodes to block any spikes & earth faults. Also have another mains auto charger as backup. The 100A LA batteries are connected to the Victron MMPT 30 / 12/24 solar supplied by 2by 35V max V, 340W panels. (wish I could afford to get another 2 of these) Output on full moon lit night was up to 50W. I had a Renogy DC-DC 12 20A charger fitted, NFG. Fitted the Victron 18 DC-DC . Charging a Moseworth 12V 200AH Lifepo4 (Best battery buy on reviews for price & support at the time) I have set this up to keep a constant charge of 13.4V, Now changed to 14V, it is holding the charge well, I run outside lights, garage 12 volt lighting & PTC heating for winter & comfort, compared to the Ren this is keeping the charge stable. took all charging off the Lifepo4 & then switched on the Victron DC-DC on magic. I have a YZPOWER 14.6V 20A LiFePO4 charger as backup connected to the Lifepo4 in parallel with the Victron, works well with both switched on both work together. I have a test discharger 12V 15A, When I switch everything on the Ferrite core Dc meter shows full charge current on the 18A charger. There were 5 massive trees blocking sunlight, Lady at the back on the south end of house has removed them so I would say 200% more sunlight, if not more, winter will tell. Comments: 1. Victron is expensive, you pay for what you get. Wish I could afford the Victron batteries. Life of LA 5 years compared to Lifpo4 8 to 10 years 2. If you can go for Lifpo4 batteries, LA do not last, there are ways to regenerate LA batteries, look it up, time consuming as in 4 to 5 days, difficult, need new acid (UK you need a licence) 3. Will either sell or use the Ren charger on my system in the study. 4. Reason for 4 stars, Never give 5 till proved. 5. Pity it does not have the blue tooth socket. It is working VERY well. You pay for what you get. 5 stars. Brilliant. Best buy I made.
