    • Better than Renogy
Originally I bought the Renogy DC to DC charger to save some money but it stopped working after 3 times using it. The Victron was much easier to set up, smaller, lighter, has bluetooth, and worked right out of the box without having to fiddle with dip switches like Renogy’s. It instantly started charging my LiFePo4 battery in my Jeep and auto-detected when the engine was on and off. I also looked at Pectron and Redarc but this one seems to be the best option in my opinion. ... show more

    • Works in my application
Set this up to charge my start stop battery from the house battery when the engine was not running and the house charger was turned on. The customizable settings and the on off sensor made this set up quite easy.

    • Perfect for charging trailer battery from tow vehicle
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. ... show more

High-quality item, easy installation. It started right up. It will be a while before I know if it works well.

    • It works, not as feature rich as I'd been led to believe
The 'manual' that comes with the unit in the box requires a magnifying glass to read. I don't have one, so I didn't. I'm not seeing ways to limit charging current, unless I have to create a custom battery setup to do that (haven't looked). I'm using this between the battery ion my two vehicle and the battery in my trailer via the 7-pin connector. I noted that even with the key off, if the trailer wiring was connected then it was also connected to the vehicle battery. Should I ever forget to unplug that for some reason when stopped for a couple days (or even overnight somewhere cold where I must run the heater) then it would drain the tow vehicle battery down, potentially leaving me stranded. This should correct for that. It only charges when the input voltage is higher, and it seems to do a very good of detecting that. I've also noted MPPT-like functionality where it boosted the input voltage to bulk charge the output battery for a time (input was 13.8v, was boosted to 14.1v to the trailer battery). Nice to see. Otherwise, via the phone app, there isn't much else to it. It has a power supply mode besides being a battery charger. But I've not looked at and likely won't ever use that function. Paying extra for the Bluetooth gives me a bit of data, namely voltages in and out, but little else other than selecting the type of battery to set the charging parameters. Sure there is a graph, but I'll probably never use that either unless there is a problem I'm trying to troubleshoot, and even then likely not. Save the few bucks and get the non-Smart version. You can still set parameters via little switches and get the same performance at a lower cost. Still, happy to have purchased my first Victron product. I expect it to function for many years to come based on brand reputation alone. ... show more

    • 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. ... show more

    • Always the best
Victron make "bulletproof" products though their in country customs service is almost non- existent. Luckily you can get most of your help online.
