Description

The Shorai LFM18A1-BS12 is a 12V, 270 CCA LiFePO4 Powersports battery, designed as a lightweight and high-performance replacement for traditional lead-acid batteries. Weighing a mere 2.38 pounds, this Lithium Iron Phosphate battery delivers robust starting power without compromising performance. Featuring Shorai's proprietary eXtreme-Rate Lithium Iron prismatic cells (LiFePO4 chemistry), this battery offers numerous advantages over lead-acid alternatives. It contains no hazardous lead or acid, and crucially, it does not produce explosive gases during charging. These batteries are also characterized by extremely low self-discharge rates, meaning they can hold a charge for up to a year without maintenance, and they do not suffer from sulfation. The expected service life is twice to four times that of lead-acid batteries. Enhanced with the Shorai Sentry BMS (Battery Management System), this battery actively monitors voltage to prevent over-discharge. If the voltage drops below a safe threshold, the BMS will automatically disconnect the terminals, safeguarding the battery from damage. This advanced feature ensures longevity and reliability. Constructed with a military-spec Carbon Fiber Composite Case, the Shorai LFM18A1-BS12 is built for durability. It offers faster cranking for more reliable starts, especially in colder temperatures, and boasts a super-fast recharge rate. While recommended for use above 0 degrees Celsius, this battery may require included foam spacers for a precise fit in certain applications.
