The REDARC Smart Start® SBI12D is a microprocessor-controlled dual battery isolator used in a dual battery system. It’s manufactured for use as a solenoid priority system to protect the start battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads.

Dual sensing

The SBI12D provides 12 volt DC incorporating 100A of continuous ratings and is designed for heavy-duty operations. The dual sensing model is compact and easy to install. It isolates the start and auxiliary battery in a system where the auxiliary battery may be charged by an external source. The SBI12D also allows the start battery to be charged by the external source after the auxiliary battery reaches 13.2V.

Power saving technology

The power saving technology includes fault detection and LED indication of operation to warn users of voltage drops, over-voltage, or excessive current draw conditions. The SBI12D has components that prevent the solenoid from generating high voltage transients. It’s better than a diode battery isolator based on the the voltage drop associated with a diode type isolation.

Surge protection

The SBI12D has full surge protection and is used primarily in 4WD and commercial vehicles. Choose the SBI12D for a safe way to charge an auxiliary battery. The SBI range manages battery charge for your secondary battery banks while on the move.

Features:

  • Overmold design
  • Compact size and easy installation
  • Silver contacts for longer life and suitable for marine applications
  • Power saving technology
  • Fault indication
  • Fully surge protected

    The best freetoes socks ever
    Color: Black, Grey
    Love this toeless socks so much! I could wear it all day. Very comfortable! It is just the right thickness which is suitable in summer time or cold weather as well. Most of the toeless socks I have seen have the gel on the heel area and I don't like the feel of it. I'd rather apply lotion on my heel then wear the socks. I have had some issues with the packaging from Amazon and I made the maker of this said socks aware of it. Julia Bebben was very prompt in her response and very helpful. Thank you Julia for your excellent customer service.

    great concept, just one tiny annoyance...
    Color: Black, Grey
    i love that a sock that lets your toes be free is even a thing that exists. i love that this company was started by a young girl, now turned young businesswoman. i have pain in my big toes, so i can't wear close toed anything, but feet get stinky if you wear shoes/slippers all the time without socks. this is a great solution. the only thing i find slightly annoying (not enough to stop using these) is the seam on the bottom of your foot, near the base of the toes. it is a straight line, which is fine on the top of the foot, but i wish the bottom itself curved a bit, to follow the line of the toes. as it is, the seam lands right in the middle if the ball of my feet, so i can feel the seams everytime i take a step. i am constantly pulling the seam toward the toes, to try to keep from feeling it, but then my pinky toe gets caught and balled up on the inside. outside of that slight annoyance, they're comfortable and fit well.

    A little expensive but really come in handy!
    Color: Black, Grey
    So far I am really happy with these socks. I broke my big toe and had to have my toenail removed and am wearing a post-op shoe/boot. I wanted to wear a sock underneath so that my foot wouldn't get too sweaty but my toe is still too tender for regular socks and cutting the toes off of regular socks doesn't work because they won't stay put. These work great- I actually pull them up over my little toes and just leave my first couple of toes exposed. I really like that you can wear these on either foot (unlike some open toed socks that have openings for the big toe and the rest of your toes so they are designated for left and right foot) since I'm only using them on my right foot.
