{"product_id":"enerdrive-b-97xd-24-120-ig","title":"Balmar 24V 120A 97XD Series Alternator, 4in Saddle Mount, K6 Pulley, Isolated Ground","description":"\u003ch2\u003eHigh-Output 24V 120A Heavy-Duty Power Generation\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003e97XD Series 24V 120A Alternator\u003c\/strong\u003e is engineered for demanding marine, commercial, and off-grid mobile power applications where standard automotive charging systems struggle to keep up. Delivering a substantial 120A output at 24V, this unit is designed to service extensive house battery loads, including lithium (LiFePO4), AGM and gel banks when paired with a Balmar multi-stage regulator. The 97XD Series uses braided-stator technology to deliver strong power at low RPM. Unlike standard units that quickly overheat under continuous load, the 97XD Series is built to sustain elevated power demands over extended operating periods, making it a strong upgrade for vessels and expedition vehicles operating in tough Australian conditions.\u003c\/p\u003e\u003ch3\u003eIsolated Ground Architecture for Corrosion and System Protection\u003c\/h3\u003e\u003cp\u003eA critical feature of this model is its \u003cstrong\u003eIsolated Ground (IsoGrd)\u003c\/strong\u003e design. Standard alternators use the outer metal casing as the negative return path through the engine block. In marine environments or complex commercial vehicles, passing high electrical currents through the engine block and hull can accelerate galvanic corrosion, damage sensitive onboard electronics, and create ground loops. By providing a dedicated, isolated negative terminal, this alternator keeps the charging circuit completely separate from the engine chassis. This significantly reduces the risk of stray current corrosion in steel or aluminium hulls and ensures a clean, stable electrical environment for modern engine management systems and navigation equipment.\u003c\/p\u003e\u003ch3\u003ePrecision Mounting and Heavy-Duty Drive\u003c\/h3\u003e\u003cp\u003eDesigned for secure integration into heavy-duty engine bays, this alternator features a robust \u003cstrong\u003e4in (Approx. 101.6mm) saddle mount\u003c\/strong\u003e configuration. The dual-foot J-180-style saddle design, typical for Caterpillar, Cummins, Detroit Diesel and John Deere engines, distributes mechanical stress across the mounting bracket. Power transfer is handled by a factory-installed \u003cstrong\u003eK6 serpentine pulley (6-groove)\u003c\/strong\u003e, which provides superior belt grip compared to traditional single V-belts. This multi-rib design reduces belt slippage, lowers heat generation, and prevents premature belt wear when the alternator is placing a heavy mechanical load on the engine during bulk charging phases.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Amperage 24V Output:\u003c\/strong\u003e Delivers up to 120A to rapidly replenish large house and auxiliary battery banks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolated Ground (IsoGrd) Design:\u003c\/strong\u003e Prevents stray current corrosion in marine hulls and protects sensitive vehicle electronics via a dedicated ground return.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4in (Approx. 101.6mm) Saddle Mount:\u003c\/strong\u003e Provides rigid, vibration-resistant mechanical mounting suitable for heavy diesel and marine engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eK6 Serpentine Pulley:\u003c\/strong\u003e Ensures efficient torque transfer and minimal belt slip under high electrical loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Duty Design:\u003c\/strong\u003e Balmar designs the 97XD Series for heavy duty cycle applications and extended duty operation, using braided-stator technology for strong output at low RPM.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Regulation Required:\u003c\/strong\u003e Designed for use with a Balmar multi-stage regulator.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cp\u003eWhether you are refitting a commercial fishing vessel, upgrading a bluewater cruising yacht, or building an overland expedition truck, the 97XD Series offers the reliability required for remote operations.
