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

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 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

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

Works great for adding a second battery (LiFePO) to my truck for amps and accessories. No troubles so far, and monitoring with phone via Bluetooth is cool feature and adds easy config option.
