Featuring a robust 3.15in (approx. 80mm) dual foot saddle mount, this high-output alternator is designed as a charging upgrade for engines requiring substantial DC power generation. Whether you are running large inverter loads, air conditioning, or rapidly recharging a high-capacity lithium (LiFePO4) battery bank, the XT Series delivers consistent, reliable amperage where standard automotive alternators fall short.\u003c\/p\u003e\u003ch3\u003eSolving the Challenges of High-Load Battery Charging\u003c\/h3\u003e\u003cp\u003eStandard factory alternators are typically designed for intermittent loads and can quickly overheat and fail when subjected to the continuous, low-resistance charge acceptance of large AGM or lithium house battery banks. Its braided-stator design and dual-fan, high-airflow frame help reduce the risk of overheating and premature component failure. By upgrading to a dedicated high-output alternator, you reduce engine run-time required for battery charging, saving fuel and minimising engine wear during off-grid stays or at anchor.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMassive 250A Output at 12V:\u003c\/strong\u003e Provides rapid bulk charging for large deep-cycle and lithium battery banks, significantly reducing generator or main engine run times.\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 you to match the exact belt profile and drive ratio required by your 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 heavy charging.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePulley Selection and Compatibility\u003c\/h3\u003e\u003cp\u003ePlease note that this unit is supplied \u003cstrong\u003ewithout a pulley\u003c\/strong\u003e to allow for custom configuration based on your engine's belt drive system.
