Victron EnergyVictron Energy Orion XS Smart DC to DC Battery Charger 12/12 50A (700W) - IP65 Dust & Waterproof - Fully Configurable - Remote Management Possible - Advanced Battery Protection

I have a 2022 Winnebago Micro Minnie FLX travel trailer with 570 Watts of Solar Panels and a 30-amp Solar Charger charging a single 320-amp LiFePo battery. Since I don’t have much of a footprint on the trailer roof for more solar panels, I decided to install a DC-to-DC Charger so my truck could charge the trailer house battery while I was driving, much like camper vans do with built in DC-to-DC Chargers. After doing hours of research and watching a lot of YouTube videos to find the best charger, I settled on the Victron Orion XS 50-amp DC-to-DC Charger. To say I’m extremely pleased with this Victron Charger would be a huge understatement. It has worked beyond my greatest expectations!One problem I did have to overcome was finding the best way to run the input wiring to the Charger from my 2022 Chevy Silverado 2500HD Diesel truck’s primary battery. I finally settled on using 175-amp Anderson connectors to provide the connection between the truck and the trailer and ran Spartan Power 2-AWG welding cables from the truck battery to the truck side Anderson connector and the same gauge cable from the trailer side Anderson connector to a Joinfworld Heavy Duty 400A Bus Bar Distribution Block near the Victron DC-to-DC charger. From the Distribution Block, I transitioned down to Spartan Power 4-AWG welding cable to make the final connection to the Victron charger. To provide further abrasion/heat protection for the positive and negative cables, I double jacketed both 2-AWG welding cables with 1 layer of GEARit 1-1/2” Heat Shrink Tubing and 1 layer of 1-3/8” Automotive Heat Shrink Braided Sleeving. I also incased the truck side Anderson connector in a Trailer Vision Anderson Connector Plug Cover surface mounting kit and the trailer side Anderson connector in a Trailer Vision Anderson Connector Cover Assembly to provide better dust/water protection. Finally, to provide proper circuit protection, I installed a BOJACK in-Line ANL Fuse Holder with 150-Amp Fuse for the positive cable from the truck battery and 2 Young Marine 60-Amp Circuit Breakers for the positive Input and Output of the Victron Charger.I highly recommend the Victron Orion XS 50-amp DC-to-DC Charger. It operates as advertised and the Victron Connect app makes it very easy to setup the charger for various batteries and battery manufacturer settings and to monitor the status of the charging while driving down the road. I’ve even used my truck to charge the battery while boondocking when the solar panels weren’t providing enough charge on very cloudy days. A very nice bonus!

Used to convert Dodge 3500 camper to lifepo4. Amazing the amount of control for volts and amps. Works great, can't imagine anything better. Moved batteries inside under rear pass bed and mounted there. Only using 40 w charging per batteries spec and it didn't get warm. Only used it one time on a short trip so far. Don't know why equipment manufacturers don't make connections a little larger. Tight fit using 6awg and octagon ferrule crimper. Nice and compact.

Installed two of these on my dual-outboard boat, both of them charging the same lithium house battery. They are easy to install and configure (via Bluetooth and the Victron app). The automatic engine shutdown detection works really well.Although you can install up to 4 AWG cables to them, I would recommend that you plan your installation wire lengths so you can use 6 AWG or even 8 AWG cables instead, with hex-crimp ferrules.

This B2B replaced another one which was rated at 40 amps and was almost four times larger! This B2B is so efficient and compact plus the app which is easy to use to set the charge parameters on the batteries you have.

I ordered this to make a mobile auto battery charger for car dealerships. It pushes 0-40A with ease and runs cool as a cucumber. No fan, no fins, just an incredibly efficient switching converter. App is nice too! Well made/well thought out. A joy to use.

Perhaps a bit more separation between positive and ground terminals to allow different kinds of adapters and cable types. In addition upon placing the key it would be helpful to know the exact settings to adjust so that the deep cycle assists a bit with cranking. My use case is merely restricting the current between the deep cycle and protecting the alternator, but i still need the deep cycle on the out terminal to still provide equaling of voltage and assist with cranking. Ill update to 5 stars once someone assists with info settings ect.

I hooked this up to my factory 5th gen 4runner with a factory 130 alternator. For the first 10 minutes or so I get the full 700 watts, then it goes down to a little over 400 watts. I believe this might put undue wear on my alternator, so I am going to be turning it down to 300 watts until I get a high output alternator of about 200 amps, and do the "big three" wiring upgrade. I love the app, and have not had any issues. It's compact, doesn't get too hot, and well made. 10/10

I like Victron products and this was a very big improvement over their previous 50A charger. So far this one has not overheated or de-rated its output due to heat. Very efficient operation
