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.

Good charger
I've had this wired up in my vehicle for a few months and it's doing a great job. I've regularly seen it pushing over 40A through the battery. 45 minutes driving a day is enough to keep my fridge running 24/7. Knowing how fast I can charge the battery I wish I'd bought a smaller one!
