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 SG2-0100 SmartShunt is a precision current shunt designed to expand the capabilities of the Balmar SG200 Battery Monitor System. This high-capacity shunt accurately measures current flow up to 350 amps, making it ideal for monitoring house banks, starter batteries, or other independent battery systems on vessels with 12V to 48V DC electrical systems.

Key Features:

  • 350 amp current measurement capacity for high-load applications
  • Compatible with 12V, 24V, 36V, and 48V DC systems
  • Precision shunt technology for accurate battery monitoring
  • Integrates seamlessly with Balmar SG200 display systems
  • Allows monitoring of multiple independent battery banks
  • Marine-grade construction for reliability in harsh environments

Each SmartShunt connects to the SG200 display unit to provide real-time monitoring of battery voltage, current, amp-hours consumed, and state of charge. One shunt is required for each battery bank you wish to monitor independently. Ideal for sailboats, powerboats, RVs, and off-grid applications requiring professional-grade battery management.
