  • 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. ... show more

  • Fast shipping
Product arrived in perfect condition, Redarc BCDC40A but have not set-up charging system yet, still waiting for other needed parts from other venders. This charger has a excellent reputation so hopefully once set up it will work as it is supposed to. 5 stars for fast shipping and sales of quality products. ... show more

  • Keeps my auxiliary battery topped off
Best investment. No more separate isolator, no separate solar controller, just 1 small simply wired charger.
