The Redarc SBI224 is a dual battery isolator designed to safely manage charging between two batteries in 24-volt electrical systems. It ensures your start battery is protected while allowing your auxiliary battery to charge automatically when the engine is running.

Built tough for harsh environments, the SBI224 features solid-state electronics and surge protection to handle heavy-duty applications. It is ideal for use in commercial vehicles, trucks, 4x4s and heavy machinery.

The isolator engages when the main battery voltage rises during charging and disconnects when voltage drops, preventing your start battery from being drained by accessories connected to the auxiliary system.
