Works flawlessly, and fantastic customer support!
This unit is built like a tank! Easy to install, just make sure you follow the instructions to the letter. I initially hooked up the grounds to both of my batteries and this does not work. Must be vehicle or frame grounded. Also do not cheap out on resettable 60 amp breakers. They overheat and trip. I then bought the recommended 60 amp blade fuse breakers from Redarc and the whole setup works amazingly! Full 50 amp charge going to my RV battery bank. Service was also off the charts as I had questions about my initial set up. Absolutely worth the money over the other DC to DC chargers available.

What can I say, it's a Redarc
That name alone should make the buying decision. Not the cheapest, but the quality is unmatched. Would buy it again in a heartbeat if needed.

I wouldnt use anything else.
I travel the USA in a 97 toyota land cruiser 80, And the Redarc keeps my auxiliary lithium battery topped off and ready to go, and it doubles as an MPPT to handle the solar panels up top when the truck isnt running.

Excellent Product!
This is the best way to isolate your Starter Battery and your Auxiliary Battery. It automatically handles direct Solar Power connectivity.
