Shorai LFX19A4-BS12 Lithium Battery – Lightweight Power, Built for Performance
The Shorai LFX19A4-BS12 is a high-performance lithium iron phosphate (LiFePO4) battery engineered for riders who demand more from their machines. Whether you're powering a sportbike, dual-sport, or adventure motorcycle, this battery delivers exceptional cranking power, long life, and ultra-light weight—all in a compact, drop-in package.
One of the standout features of the LFX19A4-BS12 is its dramatic weight reduction—up to 4 to 5 pounds lighter than many comparable lead-acid batteries. That kind of weight savings translates into noticeably improved handling, braking, and responsiveness, especially in performance or off-road riding scenarios. This battery is also sealed, non-spillable, and can be mounted in any orientation, offering more installation flexibility than traditional batteries.
With 19 amp-hours of Pb-eq capacity and cold cranking performance equivalent to 270 CCA, the LFX19A4-BS12 ensures fast, reliable starts even in cold or variable climates. Its low self-discharge rate means it can sit for months without needing a recharge—ideal for seasonal bikes or infrequent use.
To perform at its best, the battery requires a charging system output of 13.1 volts or higher at idle, and must not exceed 15.2 volts at maximum. A Shorai-compatible charger is recommended for periodic balancing and optimal longevity. You’ll also benefit from Shorai’s internal Battery Management System, designed to deliver stable, consistent power with built-in safety.
Whether you're commuting, racing, or exploring remote terrain, the Shorai LFX19A4-BS12 is a premium battery that upgrades your entire riding experience. It’s not just a replacement—it’s a performance enhancement.
