Pro Mariner 23124 ProIsoCharge Battery Isolator 120 Amp 12V 1-to-3 Banks

The Pro Mariner ProIsoCharge 23124 is an intelligent alternator power distribution system designed to charge multiple battery banks simultaneously while protecting your engine start battery. This digitally controlled battery isolator delivers zero voltage loss isolation and charging for up to 3 battery banks from a single alternator input.

Key Features:

• Digital zero voltage loss technology eliminates the typical 0.6V drop associated with traditional diode isolators, ensuring faster charge times and fully charged batteries
• Intelligent software provides priority charging to battery banks under load while taking fully charged batteries offline
• Automatic engine battery health priority ensures your starting battery is always protected
• Real-time LED status indicators show alternator power presence, battery bank charging status, and fault conditions (high/low output, over-voltage protection)
• Ignition controlled activation—only operates when ignition power is on
• Advanced regulator ready with remote sense connection for precision alternator control
• Built-in safety: ignition protected and waterproof to IP66 rating
• Modular design with included terminal stud insulator boots and snap-on protective safety cover for easy installation

Specifications:

• System voltage: 12V DC
• Maximum current: 120 amps
• Alternator inputs: 1
• Battery bank outputs: 3
• Dimensions: 6.15" L x 5.875" W x 3.125" H
