- UNRIVALED PERFORMANCE ADVANTAGE: Massive 650CCA provides instantaneous, high-velocity cold starts for heavy V-Twin engines. At 4.5 lbs (2.04 kg), this LiFePO4 unit is 75% lighter than the cumbersome 21lb lead-acid YTX30L-BS, drastically lowering your center of gravity for improved flickability, tighter cornering, and reduced suspension wear.
- PRECISION PHYSICAL SPECS & FITMENT: Designed with exact dimensions of 6.54x4.96x6.89in (166x126x175mm) to ensure a seamless drop-in replacement for YTX30L-BS, 66010-97C, and 66010-97B. Polarity: [- +]. Built with reinforced, high-conductivity terminals designed to withstand the extreme vibration of high-displacement cruiser engines without loosening.
- INTELLIGENT SMART BMS & DIGITAL READOUT: Integrated Battery Management System features an onboard, high-contrast Digital Readout LCD. Access real-time voltage telemetry and State-of-Charge (SOC) at a single touch, eliminating the need for multimeters. The BMS actively prevents over-charge, over-discharge, and manages cell balance to ensure a 2500+ cycle lifespan.
- OPTIMIZED HARLEY TOURING APPLICATIONS: Specifically engineered for the demanding starters of Harley-Davidson Touring models (1997-2024), including Street Glide, Road King, Electra Glide, and Ultra Limited. Its ultra-low self-discharge rate (<1% per month) ensures your cruiser is ready for the open road even after months of unattended winter storage.
- UTV/ATV OFF-ROAD RESILIENCE: Built to endure the high-torque ignition requirements of the Polaris Ranger 800, RZR 800, and Sportsman 850. Advanced internal cell stabilization protects against the constant mechanical shocks and G-forces experienced during aggressive rock crawling and high-speed desert trail riding.
- IP66 WATERPROOF & RUGGED DURABILITY: Fully sealed, shock-proof housing boasts an IP66 rating, providing total protection against torrential rain, deep mud, and high-pressure power washes. This robust construction is essential for snow plowing and extreme outdoor environments where standard AGM batteries frequently succumb to moisture.
- STRICT VOLTAGE & CHARGER COMPATIBILITY: Exclusively for vehicles with a qualified regulator delivering a stabilized output under 15.0V. Systems with faulty charging or output >15V (common in vintage or un-regulated stators) must be upgraded to a certified regulator to prevent BMS protection triggers. Use ONLY dedicated LiFePO4 chargers; never use lead-acid chargers with desulfurization or pulse-repair modes.
