The XT Series 170A 12V Alternator is engineered for the high-load demands of large house battery banks, including modern lithium (LiFePO4) and deep-cycle AGM configurations. Featuring a compact, small-case frame and a 1-2 inch (approx. 25.4mm or 50.8mm) single foot (spindle) mount, this high-output alternator delivers substantial amperage where engine bay space is at a premium.\u003c\/p\u003e\u003ch3\u003eWhy Upgrade to a Dedicated High-Output Alternator?\u003c\/h3\u003e\u003cp\u003eStandard factory alternators are primarily designed to maintain starting batteries and run basic vehicle electronics.
