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.

Pricey, but worth it...
I've installed 20 DC-to-DC converters. This is it. At $475, or whatever, easily $150 more than similar, it is quality. And you can mount it almost anywhere saving valuable protected space. Simple to install, virtually not setup and works as advertised. Smaller than the 50A Kisae and no fan. This is the 40A version but I'm reasonably sure the 50A is equally good.
