REDARC Dual Sensing Smart Start Battery Isolator 12V 100A

The REDARC Smart Start SBI12D 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. The SBI12D operates at 12 volt DC with a continuous rating of 100A and is built for heavy-duty use.

This compact dual sensing model is easy to install and isolates the start and auxiliary battery, allowing charging by external sources. After the auxiliary battery reaches 13.2V, the start battery can also be charged.

• Fault detection with LED indicators for voltage drops and excessive current
• Full surge protection for reliable operation
• Better than diode isolators due to lower voltage drop
• Commonly used in 4WD and commercial vehicles
• Efficient battery management while on the move
