Battery Isolator 200 Amp 12V REDARC

$345.00 $395.00

The Battery Isolator 200 Amp 12V REDARC. REDARC Smart Start® SBI212D is a microprocessor-controlled dual battery isolator used in a dual battery system. It is designed to be used as a solenoid priority system to protect the start battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads. The SBI212D Battery Isolator 200 Amp 12V REDARC  provides 12 volt DC incorporating 200A of continuous ratings and is designed for extremely heavy-duty operations.

Dual Sensing

The dual-sensing model has the added feature of allowing charge both ways where the auxiliary battery may also be charged by an external source such as Solar panels or an external AC battery charger. The SBI212D will also allow the start battery to be charged by the external source once the auxiliary battery reaches 13.2 volts to help top up the start battery.

Power Saving Technology

The Smart Start SBI212D Battery Isolator 200 Amp 12V REDARC  incorporates electronic components that will prevent the solenoid from generating high voltage transients. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. It features sophisticated fault detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions.

Used primarily in 4WD and commercial vehicles, the Smart Start SBI is a safe way to charge an auxiliary battery and should often be installed with a high quality fuse kit.
