REDARC Smart Start SBI Battery Isolator - 12V 100A

The REDARC Smart Start SBI12 is a microprocessor-controlled battery isolator which protects the start battery from excessive discharge, while allowing the auxiliary battery to supply charge to non-essential loads. It is used as a solenoid priority system in dual battery systems and provides 12V DC incorporating 100A of continuous ratings. The SBI range manages battery charge for your secondary battery while on the move. The battery isolator is mostly used in 4WD and commercial vehicles. It incorporates electronic components that prevents the solenoid from generating high voltage transients. Due to the voltage drop associated with diode type isolation, it's better than a diode battery isolator. A low standby current draw and fault detection and LED indication of operation warns users of faults such as voltage drops, over-voltage, and excessive current draw conditions. Safely maintain the charge your dual battery system with the Smart Start SBI12 battery isolator. Due to the voltage drop associated with diode type isolation, it's better than a diode battery isolator

• 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
• Power-saving technology that provides cost-effective protection for the primary battery in a safe and convenient way by using the alternator to charge the auxiliary battery.
• Protect the starter battery's excessive discharge, allowing your auxiliary battery to power your accessories.

The REDARC Smart Start SBI12 is a microprocessor-controlled 12V battery isolator designed for dual-battery systems in 4WDs, commercial vehicles, boats, and other powersports applications. With a 100A continuous rating, it uses the vehicle’s alternator to charge the auxiliary battery while protecting the starter battery from excessive discharge. This solenoid-priority system allows the auxiliary battery to supply power to accessories and other non-essential loads without compromising reliable engine starting. Part number RDCSBI12 provides a practical alternative to diode-style battery isolators by minimizing the voltage drop commonly associated with diode-based systems.
The SBI12 features power-saving technology, low standby current draw, and fully surge-protected electronic circuitry. Its overmolded design supports compact installation, while silver contacts promote extended service life and make the isolator suitable for marine environments. Built-in fault detection and LED operation indication help identify conditions such as voltage drops, over-voltage, and excessive current draw, providing useful visibility during installation and operation. Electronic protection also helps prevent high-voltage transients from being generated by the solenoid.
