The REDARC Smart Start SBI224 protects the start battery from excessive discharge while the auxiliary battery supplies non-essential loads in dual battery systems. It provides 24 volt DC with 200A of continuous ratings, making it ideal for heavy-duty operations.

This battery isolator is commonly used in commercial vehicle dual battery systems. It incorporates electronic components to prevent high voltage transients and is preferred over diode battery isolators due to reduced voltage drop.

• Features:
• Sophisticated fault detection
• LED indication of operation
• Warnings for over-voltage and excessive current draw
• Safe charging for dual battery systems
