Balmar XT-CR alternator KIT -12V – 170/250A

The Balmar XT-CR Alternator Kit is the ultimate, all-in-one charging solution designed specifically for modern Yanmar Common Rail (post-2013) diesel engines. Rather than just replacing a part, this kit provides a complete, integrated “smart” charging system that maximizes battery health, decreases engine run time, and ensures your vessel has reliable power for even the most demanding house loads.

The Complete Charging System

Buying a high-output alternator is only half the battle. To truly benefit from that power without damaging your batteries or the alternator itself, you need intelligent regulation and thermal monitoring. This kit includes everything you need for a professional-grade installation:

• Balmar XT-CR High-Output Alternator: Features the innovative braided stator design for maximum output in a compact 3.15″ saddle mount frame.
• MC-618 Digital Regulator: The “brains” of the system. This multi-stage regulator communicates with your batteries to provide the exact voltage they need at every stage of the charge cycle.
• Alternator & Battery Temperature Sensors: Critical safety components that automatically reduce output if the alternator gets too hot or stop charging if the battery reaches dangerous temperatures.
• Wiring Harnesses: High-quality, color-coded harnesses to simplify installation and ensure secure electrical connections.

Why Choose the XT-CR Kit?

• Designed for Yanmar Common Rail Engines: Yanmar Common Rail Engines require a 3.15″ (80mm) saddle mount (Hitachi style) with the Positive power post extending from the rear of the alternator.
• Lithium (LiFePO4) Ready: The included MC-618 regulator features a dedicated Lithium charging profile. When combined with the temperature sensors, it provides the precise control and safety safeguards required to charge modern Lithium banks safely and efficiently.
• Unrivaled Idle Performance: Cruising often involves low-RPM maneuvering or idling at anchor. While standard alternators produce very little at low speeds, the XT-Series is designed to deliver industry-leading output at idle, ensuring your batteries are charging the moment you start the engine.
