About This

• SUPERIOR CRANKING PERFORMANCE: Delivering a potent 420CCA—double the starting power of standard lead-acid 51913 batteries. Provides crisp, reliable ignition for BMW and Moto Guzzi engines even after long periods of seasonal storage.
• ULTRA-LIGHTWEIGHT PERFORMANCE: At just 2.4 lbs, it is 80% lighter than traditional 51913 batteries. This weight savings instantly improves the agility and suspension response of classic models like the BMW K75 and R1100GS.
• PRECISE DIN 51913 DIMENSIONS: Measuring 7.24 x 3.19 x 6.73in (184x81x171mm), this unit is a direct drop-in replacement for the original battery tray. No modifications or spacers are needed for a secure, professional installation.
• INTEGRATED VOLTAGE LCD: Features an onboard LCD Digital Readout for real-time voltage monitoring. Easily verify your state of charge and electrical system health without the need for external multimeters.
• BMW R & K SERIES COMPATIBILITY: Optimized for the BMW R1100RT (1993-2005), R1100GS (1994-1999), and K75/K75RT (1992-1996). Provides consistent voltage for reliable starts and stable electronics on legendary "Brick" and "Oilhead" platforms.
• MOTO GUZZI ADAPTABILITY: Perfect for the Moto Guzzi California 1100 (1997-2013) and Stone models. The shock-dampening LiFePO4 architecture prevents internal failure caused by the heavy vibrations of big-twin engines.
• SMART BMS TECHNOLOGY: Internal BMS manages cell health and guards against over-charge, deep discharge, and overheating for 2500+ cycles. Requires a regulated charging system BELOW 15.0V. Use ONLY LiFePO4 chargers to ensure safety.
