Product Details

The REDARC Smart Start SBI212 is a heavy-duty battery isolator designed to protect your starting battery from excessive discharge while powering auxiliary loads. This 12-volt DC isolator features a continuous rating of 200 amps, making it ideal for commercial vehicles, RVs, marine applications, and demanding off-road setups requiring reliable dual battery management.

Advanced Power Saving Technology

Engineered for extreme duty cycles, the SBI212 uses a solenoid-based priority system with integrated electronic components that prevent high voltage transients. Unlike diode-style isolators that suffer from significant voltage drop, this smart isolator maintains efficient charging performance between your primary and auxiliary batteries.

Intelligent Fault Detection

The SBI212 features sophisticated monitoring with LED indicators that warn of operational issues including over-voltage conditions, excessive voltage drop, and abnormal current draw. The low standby current draw ensures minimal parasitic drain on your battery system when not in active use.

Key Features:

  • 200-amp continuous rating for high-demand applications
  • Overmolded design for superior environmental protection
  • Silver contacts provide extended service life and corrosion resistance
  • Marine-grade construction suitable for harsh environments
  • Compact footprint for easy installation in tight spaces
  • Comprehensive surge protection circuitry
  • Visual LED fault indication system
  • Power-saving technology reduces unnecessary battery drain

The REDARC SBI212 Smart Start battery isolator provides a safe, efficient solution for maintaining your secondary battery in dual battery systems, ensuring reliable power for accessories while protecting your ability to start your vehicle.

So far, no problems? Will see how it goes?

Great

Great as always!!!

As long as i recieve the part in a timely fashion this would be rated a five. Site is strange, had truck as vehicle (2000 tundra) and showed no parts, but typed in part # and they came up. Also, did not get 20% coupon code as intro stated.

Have been looking for that piston for weeks, so glad you had it!

Fast &amp;Easy

Very competitive pricing (within best 2-3 prices I could find anywhere online) on a foam kayak carrier kit. Shipping was a little high relative to competition, but base price was good enough that with this stellar reputation on RR, ordering from them seemed the right way to go. Ordered 2/17, received it on 2/20 - so *excellent* performance on the delivery side. Satisfied with my decision to shop here. Will eagerly consider them again in the future.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.
