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 XT-DF4-250-DV-KIT is a complete high-output charging system that includes the XT-DF4-250-DV alternator, MC-618 multi-stage voltage regulator, temperature sensors, and mounting hardware. This 250-amp, 12-volt alternator features a 4-inch dual foot saddle mount with dual vee pulley and case ground design, making it compatible with J-180 mount applications typically found on John Deere, Cummins, and Caterpillar engines.

XT-Series Alternator Technology:

  • State-of-the-art braided wire stator design generates exceptional output in a compact package
  • Features 96 slots compared to 36 slots in traditional S-wound stators for superior electromagnetic energy and efficiency
  • Delivers up to 186 amps at idle speeds for 12V applications
  • Operates 5 to 10 degrees Celsius cooler than previous AT-Series designs
  • Smart Ready internal regulator technology provides additional fault tolerance
  • Dual fan cooling system for high-airflow performance

MC-618 Max Charge Regulator Features:

  • Multi-stage voltage regulator with user-selectable programs for deep-cycle flooded, standard flooded, gel, AGM, spiral wound AGM, Carbon Foam, and LiFePO4 batteries
  • Bluetooth-capable with integration to SG200 Battery Monitor for viewing alternator activity from color display or smartphone app
  • Modifies charging voltage to meet charge state, battery type, and temperature for faster, fuller battery charging
  • Uses active temperature regulation to maximize high-temperature output
  • Includes 54-inch wiring harness with power, field, ignition, stator, and ground wires

Important Installation Notes:

  • Must be used in dual vee or multi-groove serpentine belt configurations
  • May require a Tachometer Signal Stabilizer (Part No. 15-TSS) if your current tachometer is not adjustable
  • Temperature sensors monitor both alternator and battery conditions for optimal performance

This complete charging kit is ideal for marine, RV, and industrial applications requiring high-capacity charging systems, especially those with lithium battery banks or large house battery configurations. The compact design delivers professional-grade charging performance with advanced protection features.

Quick, easy.

Easy, seamless. Quick delivery.

I like the process of looking for the part but I just hope the part is what the pic looks like

Quick and simple process and they had what I needed.

The instructions state the need for a 13mm socket but it's a 14 that's needed. Also the spacers on the light bar are too big to use both in the bull bar. Had to split one in half. Also, absolutely ZERO instructions with the light bar installation in the bull bar was infuriating.

Easy peasy.
