It does what it claims and very well
Other than a issue with a TAX invoice as in they do not supply one a major pain In Australia if you want to claim the unit as a Business expense as is what i wanted to do. The unit is by far the best one i have tested so far. It does not just charge and cut off it also supplies power to the connected devices so as not to run the battery down when the battery is full and the sun is still shinning. So if you don't need to right this off TAX wise i would recommend it. So 5 stars for the Item 1 start for the seller.

Very happy I got this exact model
I researched for probably three months on what DC to DC charger I was gonna get. This one was highly recommended by everyone. As well as offering solar charging and coming from a reputable brand I know I can trust. I’ve been using it for about a month already and it’s worked awesome. I don’t think it’s possible to find a better deal especially for high-quality name and product like this one.

Works Great
Installed in a bus conversion to take advantage of the alternator charging my LiFePo4 batteries when the engine is running and being able to trickle charge the starter batteries while parked. Seamless installation, robust connectors and after I ordered and installed the BT-2 hardware, the app provides all the pertinent information in real time. Time will determine the durability of the device, but it's working great thus far. Cheers!

Smart purchase battery charger and mppt control in one
I upgraded my solar panel with the shade tech panel. Then found out I needed to upgrade to this 50amp dc/dc charger from my 30 amp This works well and keeps the batteries top off. If I read the instructions correctly it even charges my automotive start battery if it gets run down.

A great compliment to our trailer
Super easy to install and charges really well. Renogy make incredibly well build products and I would highly recommend. It allows us to run the fridge when travelling in our trailer on battery power without running down the battery. You do need to ensure you run the correct wire gauge for the length of your run from your vehicle battery to the charger. I would also recommend to get the appropriate circuit breakers for safety.
