Designed for marine vessels, custom 4WDs, RVs and off-grid applications, this high-output alternator provides a significant upgrade over standard factory-fitted automotive units. With a substantial 170A output at 12V, it rapidly replenishes large deep-cycle and lithium (LiFePO4) house battery banks, reducing engine run times and improving overall system efficiency.\u003c\/p\u003e\u003ch3\u003eEngineered for Reliable High-Output Charging\u003c\/h3\u003e\u003cp\u003eStandard automotive alternators are typically designed for intermittent loads and can quickly overheat when subjected to the continuous high-current demands of modern lithium battery systems and high-powered inverters. The XT Series addresses these limitations with a braided-stator design and a dual-fan, high-airflow frame. By maintaining stable output under heavy loads, this unit helps reduce the risk of overheating, premature component failure, and unexpected power loss in remote locations.\u003c\/p\u003e\u003cp\u003eFeaturing a \u003cstrong\u003eHitachi-style 3.15-inch (approx. 80mm) dual-foot saddle mount\u003c\/strong\u003e configuration, this alternator offers exceptional mechanical stability. The dual-foot design distributes engine vibration and belt tension evenly across the mounting bracket, minimising mechanical stress and alignment issues common in high-vibration marine and off-road environments.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e170A High-Amperage Output:\u003c\/strong\u003e Delivers rapid charging capabilities for high-capacity 12V battery banks, ideal for supporting heavy DC loads and inverters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.15in (Approx. 80mm) Dual-Foot Mount:\u003c\/strong\u003e Hitachi-style mounting, which Balmar lists as typical for Yanmar, Westerbeke, Lehman and Perkins-Sabre engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomisable Drive Configuration:\u003c\/strong\u003e Supplied without a pulley, allowing system builders to select the exact drive ratio and belt profile required for their specific engine setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Fan Cooling:\u003c\/strong\u003e A high-airflow frame with dual fans helps manage heat during prolonged high-output charging.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePulley Selection and Compatibility\u003c\/h3\u003e\u003cp\u003ePlease note that this XT Series alternator is supplied \u003cstrong\u003ewithout a pulley\u003c\/strong\u003e to accommodate custom belt configurations and drive ratios.
