Balmar

<h3>About Balmar: Marine DC Power Since 1981</h3><p>Since its founding in 1981, <strong>Balmar</strong> has built a reputation as one of the most trusted names in marine DC power. For over four decades, the company has focused exclusively on helping sailors and power boaters solve one of the most persistent challenges on the water: keeping batteries charged reliably and efficiently. That singular focus has made Balmar the go-to choice for serious mariners who demand more from their electrical systems.</p><h3>Innovative Alternator Technology</h3><p>Balmar's greatest claim to fame is its lineup of <a href="/12782-balmar-alternators-200087">marine alternators</a> — widely regarded as the highest-output and most dependable alternators available in the recreational marine market. What sets Balmar apart is not just raw output, but smart engineering. Their patented <strong>Smart Ready&reg; Alternator</strong> technology allows the alternator to communicate directly with an external regulator, enabling precise, multi-stage charging profiles that protect batteries and extend their service life. Whether you're running a modest weekend sailboat or a fully outfitted bluewater passage-maker loaded with electronics, Balmar offers an <a href="/12782-balmar-alternator-2412">alternator</a> sized and engineered for the task.</p><p>Marine environments are uniquely demanding — salt air, vibration, and the need for long, uninterrupted charging cycles put far more stress on electrical components than typical automotive applications. Balmar designs its alternators specifically for these conditions, with robust construction and thermal management that keeps performance consistent even during extended motoring passages.</p><h3>Battery Monitors &amp; Charging System Management</h3><p>A high-output alternator is only part of the equation. Knowing the true state of your battery bank is equally critical, which is why Balmar also produces a respected line of <a href="/12782-balmar-battery-monitors-volt-meters-200146">battery monitors and volt meters</a>. These instruments give mariners accurate, real-time insight into battery voltage, state of charge, and current flow — the kind of data that prevents being stranded at anchor with a dead house bank. Balmar's monitoring products are designed to integrate seamlessly with their charging ecosystem, giving you a complete picture of your DC system's health at a glance.</p><h3>Expert Support &amp; a Legacy of Trust</h3><p>Beyond the products themselves, Balmar has long been recognized for its exceptional technical support. Marine electrical systems can be complex, and Balmar's knowledgeable team has a well-earned reputation for helping customers spec the right components and troubleshoot installations. That combination of innovative hardware and genuine expertise is a big reason why Balmar has remained a privately held, customer-focused company for over 40 years — and why the brand continues to be found aboard everything from coastal cruisers to offshore racing yachts.</p>

Product Details

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.
