REDARC Dual Sensing Smart Start Battery Isolator 12V 200A

The REDARC Smart Start SBI212D is a microprocessor-controlled dual battery isolator designed for dual battery systems. It protects the start battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads. Its compact size ensures easy installation, and it is built for extremely heavy-duty operations.

This dual sensing model isolates the start and auxiliary battery, allowing the auxiliary battery to be charged by solar panels, an external AC battery charger, or another external source. The SBI212D charges the start battery once the auxiliary battery reaches 13.2V, featuring fault detection and LED indications for voltage drop, over-voltage, or excessive current draw.

• 200A continuous ratings for heavy-duty operations
• Full surge protection for safe charging
• Compact design for easy installation
• Facilitates additional charge via vehicle alternator
• Better than a diode battery isolator
