Product description

ULTRA-HIGH CRANKING & LIFE CYCLE: Engineered with advanced LiFePO4 cells, this 12V 4Ah battery delivers a powerful 240 CCA for instant ignition. Compared to traditional lead-acid, it offers 2,000+ deep cycles and 1/3 the weight, significantly reducing your long-term maintenance costs and improving vehicle handling.
EXACT FIT & LIGHTWEIGHT SPECS: Measuring 150x87x105mm(5.9*3.43*3.66) in(L*W*H)and weighing only 1.90 lbs, it is a perfect drop-in replacement for YTX9-BS. Features Left Hand Positive [+ -] terminal polarity and a reinforced vibration-resistant internal structure, ensuring a secure and steady fit in most mid-size motorcycle battery trays.
SMART DIGITAL VOLT MONITORING: Equipped with a real-time Digital Volt Readout on the top cover, allowing you to monitor your electrical system’s health at a glance. The integrated 60A BMS provides precision protection against over-charge, over-discharge, over-current, and ensures voltage cell balancing.
WIDE SPORTBIKE COMPATIBILITY: Precision-engineered for high-performance street bikes including Kawasaki Ninja 400 (2018-2024), Z650, Ninja 650, and Honda CBR600F4i. It provides the reliable high-current discharge required for modern fuel-injected engines and sensitive electronic components.
ADVENTURE & NAKED BIKE FITMENT: Optimized for European and Japanese naked bikes such as KTM Duke 200/390 (2013-2024), RC 390, and Suzuki GSX-R600/750. Its low self-discharge rate (less than 1% per month) makes it the ideal choice for riders who store their bikes during the winter season.
IP66 WEATHERPROOF RELIABILITY: Boasting an IP66-rated dust and water-resistant casing, this battery is built to withstand extreme riding conditions, from heavy rainstorms to dusty off-road trails. Ensures consistent starting power regardless of the environment, keeping your journey uninterrupted and safe.
VOLTAGE COMPATIBILITY & WARRANTY: Exclusively for vehicles with a qualified regulator delivering stabilized output under 15.0V. Systems using old Shunt Regulators may harm the battery; upgrading to a MOSFET regulator is highly recommended. Verify peak charging voltage (14.4V±0.2V is optimal) before use.
Customers find the battery to be of excellent quality, with one noting it performs as well as OEM units, and appreciate its lightweight design, with one customer mentioning they can feel the difference in weight while riding. Moreover, they praise its power output, with one customer noting it’s more powerful than expected for its size, and consider it well worth the money. However, the battery life receives mixed feedback – while some report it lasts up to a week, others mention it fails within 6 months. Additionally, installation is straightforward, and opinions about size and charging are mixed, with some finding it smaller than expected and others noting it comes fully charged.
