Balmar CFII1224 Centerfielder II Dual Alternator Charge Balancer 12V/24V

The Balmar Centerfielder II is an intelligent charge balancing system designed for twin-engine marine applications with dual alternators. This automatic controller monitors both port and starboard voltage regulators, ensuring balanced charging performance across your vessel's entire electrical system.

Key Features:

• Automatically balances charging output in twin-engine applications for optimal battery health
• Compatible with both 12-volt and 24-volt electrical systems
• Intelligently isolates alternators and regulators when only one engine is running
• Splits field output from the dominant regulator to both port and starboard alternators during dual-engine operation
• Includes two fused 12 AWG power wires with 15-amp ATC fuses for safe installation

When both engines are running, the Centerfielder II automatically provides field current from a single regulator to both alternators, eliminating the common problem of unbalanced charging that can lead to premature battery failure. The system seamlessly switches to isolated operation when running on a single engine, protecting your charging system components.
