For use in dual battery systems in vehicles or on boats where the (smart) alternator and the start battery are used to charge the service battery. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch and has an engine running detection mechanism. Victron Energy Orion Tr-Smart DC-DC charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries. Models are available up to 400W and unlimited multiple units can be connected in parallel to increase output power. If required, Bluetooth can be disabled.

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 340W panels.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, 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.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 years2. 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.It has worked VEY well. You pay for what you get.5 stars. Brilliant. Best buy I made.

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.

Was straight forward to wire in and set up.. I got the 18 amp version as the alternator does not have huge out put on my old Camper truck. I needed to limit the current output as I didn't want overload it. Seems to work fine but I haven't been out on the road yet so haven't really put it to the test.. I expect it will work fine

I have installed this in the battery compartment of my truck camper. I am using the 7 pin trailer connector on the truck. I had to add a section of #10 wire between the charger and the 7 pin connector in the camper. The charger would not work when first installed. It shut down a few seconds after starting due to low input voltage from the truck battery. I went through the positive side wiring and found that there were 2 unnecessary fuses in the circuit as well some sketchy crimp connections. After fixing these it is now working, but maybe "on the edge". So a good, reasonably high current connection is needed between the truck battery and the DC/DC charger.It was easy to set-up via Bluetooth (default is Lithium). Its great to be able to monitor the charge stage and input / output voltages. It would be nice to monitor the charge current as well though.Because of the way the camper is wired, I connected both negative terminals to the negative of the camper battery. It is possible that I did not need an "Isolated" version. Maybe the Non-Isolated version would have worked as well, but I was unclear on whether it would be a "smart" 3 stage charger like this one is. To be clear, I did not rely on the chassis ground. The negative is wired right from the truck.Anyway, I pretty happy with it and it even plays well with my Victron Solar Controller.

Victron op zijn best. Apparaat is in te stellen via een app.Degelijk gebouwd, en doet waarvoor hij is gemaakt. Via de app is goed de lading van beide accu's te monitoren. Zonder meer kwalitatief perfect.

Habe einen VW T5 Bj 2008 und lade meine 2. Batterie damit. Kein D+ Signal notwendig. Einfach zum installieren und dank Bluetooth, einfach zum einstellen und überwachen. Den Plus Anschluss habe ich direkt an die Startbatterie geklemmt, die Masse an die Karosserie unterm Fahrersitz. Dann mit Sicherung dazwischen an die 2. Batterie angeschlossen fertig.Tollers Gerät und sehr wertig gebaut, kein Billigsch..ss!

Great product! The only things that are missing for me are the app display doesnt show the amps in out, and it would be nice to be able to limit the charging current by way of a selection (I.e. 2,5,10,max)
