RELIABLE CRANKING POWER: High-discharge lithium cells deliver 140CCA, ensuring quick engine turnover for compact ATVs and garden equipment. Replaces traditional 4L-BS with superior efficiency. INTEGRATED DIGITAL READOUT: No more guessing battery status. The LCD Digital Readout offers instant voltage checks, ideal for equipment used seasonally, ensuring you're never stranded. VIBRATION-PROOF DESIGN: Built to withstand the constant mechanical shaking of lawn tractors and off-road quads. The robust LiFePO4 structure prevents plate damage common in lead-acid units. LIGHTWEIGHT & ECO-FRIENDLY: Weighing only 1.26 lbs, it reduces the burden on small-engine starters. A cleaner, safer, and non-spillable alternative to AGM, with a massive 2500+ cycle life. WEATHER-SEALED PROTECTION: IP66 rated for total protection against moisture and debris. Whether it’s garden work in the rain or trail riding through mud, TYKOOL ensures continuous power. MAINTENANCE-FREE CONVENIENCE: No acid packs, no leaks. This sealed lithium unit requires zero maintenance and maintains charge longer than any standard lead-acid battery during off-seasons. VOLTAGE & CHARGER COMPATIBILITY: Exclusively for vehicles with a qualified regulator (output 15.0V). TaoTao series vehicles are excluded unless a certified full-wave regulator is installed. Use ONLY dedicated LiFePO4 chargers. DO NOT use lead-acid chargers with desulfurization/pulse modes to prevent cell damage.
