Victron EnergyOrion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 30 amp 360-Watt - Battery Charger for Dual Battery Systems - Isolated

I like that this product has a bluetooth capability and that helped me alot setting it up. It is working great and charging my Bluetti. I also like the option of being able to shut it off when I shut off the engine too.

This was a great addition to our skoolie solar system. It keeps our 400ah battery bank charged as we relocate to isolated campsites. It was simple to install, the app and Bluetooth work well, and it doesn't get crazy hot while charging. Use HEAVY battery cables to get the most out of it. Having it turn itself off when the engine stops (without running a signal wore to ignition or alternator) is a real time saver.

What a problem solver. I needed to charge the 2nd 12V battery in a 24V series from the 1st 12 battery. With isolated output from input this does.The only frustration was getting the PIN correct for the Bluetooth connection. The printed instructions say "000000" but it would not connect. The next morning, I looked at the thing, and found a completely different PIN on a label on the side of it. That one worked. I've been working with chargers, inverters, alternator systems for 40 years. This thing is really cool. Very nice piece of kit.

Exactly what i needed. Replaced the previous one after a reverse polarity incident.

Update: I changed my stars I LOVE VICTRON DEVICES. I know own the battery shunt, Solar controller and DC to DC charger. Love them.RESETTING LOST PIN:If you need to reset your Victron devices, lost your pin, or whatever. Take a picture of the labels around the device before you install them and store it somewhere on a computer or phone for reference. There PIN and PUG is on the stickers.The PUG is use for resetting the PIN, its a security feature to allow only persons in physical proximity of the Victron device to reset the PIN, blocking everyone else.ORIGINAL MESSAGE: Will change my rating once I get a pin that works. Everything went well, but I am unable to enter the 000000 pin number it is asking for on initial setup. I got my phone as close as 6 inches to make sure bluetooth connects and when it ask for the pin, the same message pops back up again asking for the pin - endless loop.. Cannot get it to join the other two Victon products I own and have on my iPhone.

So as the title says, the biggest complaint is the temperature this gets. When running at full power, this thing will easily cause you severe burns. Im sure its capable of melting plastic, which I happen to have it mounted to a a plastic siding and smelled it gassing. I have found there are a couple ways to maybe control this. If you turn off the smart alternator setting and turn off the engine shutoff and turn off the hard cutoff for this, it will pull its maximum power from the alternator, which in my case was right at 410 watts. Also around 33.5 amps. Which is more than rated which is nice. However the downside, i have 2 #10 wires running to this, about 10 feet each way and it drops my voltage from 14v to 12.8 volts. Seems to be a little inefficient given the math for voltage drop, the step up converter is probably what is making all the heat at this point. If I re-enable the low voltage cutoff, and reenable the smart alternator setting, it will only pull closer to 300 watts, about 23 amps dropping the voltage to about 13.1v. Which is still more voltage drop than there should be given my pure copper dual #10 wiring. I tested this using only 1 set of #10 wires, and with the smart alternator enabled, i could only get 10-12 amps, no more than 168 watts. Im assuming that in smart alternator mode, it varies the current based on the voltage at the unit, which means that there is some incredible voltage drop at the unit. There is something definitely inefficient in the unit, and at this price point I figured I was getting something top of the line. This has to be why the unit creates so much heat. There should be an active cooler on this. Buyers should be aware of this fact. Otherwise, the item works great.

Horrible Bluetooth range. Do some Googling before you buy this. I have about 1m worth of range to this device. I installed it in my TV when I upgrade the battery system to lithium. I can connect when I stand right beside the camper, but have no connection inside the truck, which means I have no way to monitor it to see if the charge settings are even working. AND...And there is NO data logging without a Bluetooth connection, so I have no way to see if it worked afterward. I could try leaving my phone in the camper, but that kinda defeats the purpose of having Bluetooth in the first place.

The product worked great ,only issue I had was Bluetooth pairing connection kept disconnecting instead of working in the backgrounds. Made solid quality and design is worth the money for a dual battery isolator/charger.
