Antigravity AT12BS‑RS Lithium Battery w/ RESTART | Replaces YT12‑BS YT12B‑BS YT14‑BS | Fits Yamaha R6, Suzuki GSX‑R, Kawasaki Ninja, Honda CBR, Ducati, Triumph

OVERVIEW

The Antigravity AT12BS‑RS is a precision‑engineered lithium motorcycle battery designed to deliver reliable starting power, stable voltage output, and consistent cold‑cranking authority. Built around dense LiFePO4 chemistry and housed in a completely sealed configuration, this direct replacement effectively eliminates terminal corrosion and heavy lead‑acid degradation. It provides a precise electrical foundation for mid‑size street motorcycles requiring a modern performance upgrade.

ENGINEERING & PERFORMANCE

This battery delivers strong cranking performance and consistent ignition cycles by leveraging LiFePO4 chemistry that actively avoids sulfation degradation. The sealed internal construction resists vibration-induced cell failure and maintains stable voltage across temperature extremes, while the integrated BMS continuously monitors charge cycles and thermal limits. Operating as an exact dimensional replacement for outdated lead‑acid units, it secures directly into factory trays and supports vertical or horizontal mounting without electrolyte leakage.

KEY FEATURES

• Advanced LiFePO4 (Lithium Iron Phosphate) chemical architecture
• Integrated BMS for continuous cell balancing and thermal protection
• RESTART Technology enables instant self‑jump capability after complete drain
• Ultra‑light 2.3 lb construction significantly reduces unsprung chassis weight
• Rated at 12V with 360 Cold Cranking Amps
• Directly replaces YT12‑BS, YT12B‑BS, and YT14‑BS form factors
• Sealed, completely maintenance‑free design
• Secure multi‑orientation mounting support without leakage
• Stable cold‑weather operation independent of depth‑of‑discharge degradation
• YTX‑series tray compatibility with auxiliary RESTART jump terminals

WHY RIDERS CHOOSE THIS

Riders consistently select this battery because its advanced chemical architecture and full protective electronics eliminate the slow degradation and terminal decay associated with conventional lead‑acid replacements. The integrated RESTART feature quickly resolves emergency drain situations by allowing instant roadside recovery, which removes reliance on secondary batteries during remote trails or overnight rides. Its exceptionally light profile sharply reduces overall vehicle mass, easing strain on aging charging systems and improving handling dynamics across tuned street and adventure builds. By maintaining aggressive cranking output in low temperatures while occupying exact factory dimensions, it delivers dependable daily operation without added maintenance or complex installation procedures.
