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. Review: Worked with Victron for over 30 years, Great. I bought the Isolated. - 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. ## Features - Victron Energy Orion-Tr Smart 12/12-Volt 18 Amps 220 Watts DC-DC Isolated Charger is a professional 3-level adaptive DC to DC charger with built-in Bluetooth. - Suitable for lead and lithium batteries.

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 ### ⭐⭐⭐⭐⭐ Great, Simple 12/12 Charger for RV Lithium Upgrade *by J***H on 29 November 2024* 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.
