Review: Great, Simple 12/12 Charger for RV Lithium Upgrade - 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.
Review: Trusted company that has your back - 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!

## 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.

### ⭐⭐⭐⭐⭐ Total isolation between batteries and fully charged trailer battery while traveling.
*by C***Y on November 1, 2025*

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.
