GO FURTHER WITH REDARC DUAL BATTERY ISOLATORS

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. If you need some help with the set up, check out REDARC’s Smart Start Battery Isolator and Wiring Kit. It comes with everything you need to install your isolator, so you can just plug in and play. We provide plenty of helpful resources in our Support section, as well as informative blog posts, videos and more in our Discover section. The REDARC team is also on hand to answer any of your questions.
