PRO-GRADE 300CCA STARTING POWER: The PRO series delivers an upgraded 300 CCA and 5Ah capacity, designed for high-compression engines and bikes with high parasitic draw. LiFePO4 technology provides massive cranking current and 2,000+ cycles, outperforming lead-acid in both power and longevity.

PRECISION PHYSICAL DATA & FIT: 150x87x105mm(5.9*3.43*3.66in)(L*W*H) at only 2.1 lbs (approx). Featuring Left Hand Positive [+ -] polarity, it serves as a seamless drop-in replacement for YTX9-BS,GTX9-BS. The ultra-lightweight construction reduces unsprung weight, a critical advantage for track days and high-speed cornering.

DIGITAL SOC % SMART MONITORING: Features a high-definition Digital SOC (State of Charge) Readout, displaying the exact percentage of remaining energy. The integrated BMS provides military-grade protection against over-charge, over-discharge, over-current, and ensures precise cell voltage balancing.

ELITE SPORTBIKE COMPATIBILITY: Optimized for high-revving performance machines such as the BMW S1000RR (select years), Triumph Street Triple 675/765, and KTM RC 390. It supports the complex electronics and quick-shifters found on modern supersport and naked motorcycles.

MULTI-BRAND PERFORMANCE FITMENT: A perfect match for Kawasaki Z900, Z1000, and Honda CBR600RR owners seeking a weight-saving edge. Its stable discharge curve ensures that fuel pumps and ignition coils receive maximum voltage for optimal engine performance and throttle response.

IP66 SEALED FOR RACING CONDITIONS: The IP66-rated housing ensures total protection against dust and high-pressure water jets. Whether you are racing in the rain or washing off track grime, the PRO series' ruggedized case ensures your power source remains dry and fully functional in any weather.

VOLTAGE COMPATIBILITY & WARRANTY: Exclusively for vehicles with a qualified regulator delivering stabilized output under 15.0V. Avoid use with old Shunt-style regulators which can exceed 15V and damage cells; upgrade to a MOSFET regulator for best results. Verify charging voltage (14.4V±0.2V) before use.

UNLEASH PEAK PERFORMANCE WITH TYKOOL PRO SERIES Upgrade your ride with the TYKOOL LFP9-BS-PRO, the definitive high-performance lithium LiFePO4 battery designed for enthusiasts who demand more than just a start. Engineered to exceed the limitations of standard YTX9-BS lead-acid batteries, the PRO series is the ultimate power solution for modern supersport bikes, high-compression ATVs, and precision-tuned racing machines. UPGRADED 300CCA & 5AH CAPACITY While standard batteries struggle in demanding conditions, the PRO series delivers a massive 300 Cold Cranking Amps (CCA) and an expanded 5Ah capacity. This ensures lightning-fast ignition for high-displacement engines and provides the necessary energy buffer for vehicles equipped with power-hungry electronics, aftermarket lights, and advanced engine management systems. Experience consistent, reliable power delivery that lead-acid alternatives simply cannot match. SMART MONITORING: REAL-TIME DIGITAL SOC % Knowledge is power. The LFP9-BS-PRO features an integrated Digital SOC (State of Charge) Readout, allowing you to monitor your battery’s remaining energy percentage at the press of a button. No more guessing if your bike will start after long-term storage or track sessions. Combined with a sophisticated 60A Smart BMS, your battery is actively protected against over-charging, over-discharging, and over-current, ensuring total cell balancing and safety. TRACK-READY LIGHTWEIGHT DESIGN In the world of performance riding, every pound counts. At only 2.1 lbs, this lithium battery is approximately 70% lighter than its 8.2 lb lead-acid equivalent. By drastically reducing unsprung weight, the TYKOOL PRO series improves your motorcycle’s flickability, acceleration, and suspension response, making it the preferred choice for track days and aggressive canyon carving. RUGGED, WATERPROOF & UNIVERSAL FIT Built to survive the toughest environments, our IP66-rated waterproof casing ensures your power remains uninterrupted by rain, mud, or pressure washes. With a universal 150x87x105mm footprint and [+ -] Left Hand Positive polarity, it is a seamless drop-in replacement for YTX9-BS, GTX9-BS, and UT9-BS models. Perfectly compatible with elite machines like the BMW S1000RR, KTM RC390, Triumph Street Triple, Kawasaki Z900, and Honda CBR600RR. VOLTAGE COMPATIBILITY NOTE To ensure longevity, this high-performance lithium battery must be used in vehicles with a healthy charging system (stablized output <15.0V). We recommend upgrading older Shunt-style regulators to a MOSFET regulator to maintain the optimal 14.4V charge profile.
