Protect the starter battery from accessory discharge while using an auxiliary battery for non-essential loads. This voltage-controlled isolator connects the dual-battery system when its charging threshold is reached and separates it as voltage falls.
Key Features
- It is used as a solenoid priority system in dual battery systems and provides 12V DC incorporating 100A of continuous ratings.
- 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.
- 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.
Fitment
For compatible 12V dual-battery systems. Verify battery chemistry and charging-system suitability. Not a dedicated lithium battery charger.
