Featuring a robust 4-inch (approx. 101.6mm) dual foot saddle mount, this high-output alternator provides a substantial upgrade over standard factory units. It is specifically designed to support rapid recharging of large house battery banks, including deep-cycle AGM and Lithium (LiFePO4) systems, ensuring your essential onboard electronics and appliances remain powered.\u003c\/p\u003e\u003ch3\u003eEngineered for High-Output Charging\u003c\/h3\u003e\u003cp\u003eStandard automotive alternators often struggle and overheat when subjected to the continuous high-load demands of lithium battery banks or heavy inverter usage. The XT Series addresses this with a braided-stator design and a dual-fan, high-airflow frame. By upgrading to a dedicated high-amperage alternator, you significantly reduce engine run-time required to replenish depleted batteries, saving fuel and minimising engine wear during off-grid or marine operations.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh 170A Output at 12V:\u003c\/strong\u003e Delivers substantial charging current to rapidly replenish large-capacity battery banks and run heavy DC loads simultaneously.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4in (Approx. 101.6mm) Dual Foot Mount:\u003c\/strong\u003e J-180 saddle mounting, which Balmar lists as typical for John Deere, Cummins and Caterpillar engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomisable Drive Setup (No Pulley Included):\u003c\/strong\u003e Supplied with a bare 17mm shaft, allowing you to fit the Dual V or multi-groove serpentine pulley required for your specific engine belt geometry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Resilience:\u003c\/strong\u003e Built to handle the elevated thermal stresses associated with charging low-internal-resistance batteries like LiFePO4 when paired with an appropriate external regulator.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced System Risk:\u003c\/strong\u003e Mitigates the risk of stator burnout and premature failure commonly experienced by stock alternators pushed beyond their duty cycle limits.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eImportant Configuration Notes and Exclusions\u003c\/h3\u003e\u003cp\u003ePlease note that this unit is supplied \u003cstrong\u003ewithout a pulley\u003c\/strong\u003e to allow for custom drive matching.
