About This

• SUPERIOR CRANKING PERFORMANCE: Engineered with a robust 480CCA to provide rapid cold starts for large V-Twin engines. At just 3.3 lbs (1.50 kg), it is 75% lighter than the 14lb lead-acid YTX20L-BS, significantly lowering your motorcycle's center of gravity for improved flickability, easier cornering, and reduced suspension component wear.
• PRECISE PHYSICAL SPECS & FITMENT: Dimensions: 6.89x3.43x6.10in (175x87x155mm). Direct drop-in replacement for YTX20L-BS, 65989-97C,GYZ20HL,GYZ20L and ETX20L. Polarity: [- +]. Features vibration-isolated terminals and a rugged casing designed to withstand the heavy mechanical thumping and engine heat of high-performance American cruisers.
• INTELLIGENT BMS & DIGITAL MONITORING: Integrated Battery Management System features an onboard Digital Readout LCD screen. Access real-time voltage telemetry and State-of-Charge (SOC) with a single touch. The BMS actively manages cell balancing while protecting against over-charge and deep discharge, ensuring a stable 2500+ cycle life.
• HARLEY CRUISER APPLICATIONS: Specifically optimized for Harley-Davidson models including Softail, Fat Boy, V-Rod, Heritage Softail Classic, and Night Train. The ultra-low self-discharge rate (<1% per month) ensures your bike remains road-ready even after several months of unattended winter storage, outlasting traditional AGM batteries.
• IP66 WATERPROOF & RUGGED DURABILITY: Fully sealed, shock-proof housing with an IP66 rating provides total protection against torrential rain and road debris. Essential for long-distance touring on models like the Road King and Deluxe, ensuring your electrical heart remains bone-dry and functional in all-weather environments and high-vibration conditions.
• VOLTAGE & CHARGER COMPATIBILITY: Exclusively for vehicles with a qualified regulator delivering a stabilized output under 15.0V. For optimal longevity, a charging voltage of 14.4V (±0.2V) is highly recommended. Use ONLY dedicated LiFePO4 chargers; never use lead-acid chargers with desulfurization or pulse-repair modes to avoid damaging the BMS.
