REDARC’s Smart Start (SBI) battery isolators prevent your secondary battery draining your main battery, so you can stay out on the road for longer. 

Microprocessor controlled, our dual battery isolators are designed to protect the start battery from excessive discharge while allowing the auxiliary battery to supply charge to non-essential loads. The dual sensing model can also be used to isolate the start and auxiliary batteries in a system where the auxiliary battery is being charged by another source, such as 4WD solar panels. Not to mention, the isolator features sophisticated fault detection and LED indication to warn the user of faults, including over-voltage, voltage drop and excessive current draw conditions.

Easy to install and compact in size, REDARC’s battery isolators will suit all of your battery charging needs. 

Having the right dual battery system for all of your off-road adventures is essential. With a REDARC battery isolator, you can go further, explore more and always be one step ahead.
