Antigravity ATZ7‑RS Lithium Battery w/ RESTART | Replaces YTZ7S YTZ5S YTX4L‑BS YTX5L‑BS YTX7L‑BS | Fits Honda Yamaha Kawasaki Suzuki KTM Polaris Can‑Am

OVERVIEW

The Antigravity ATZ7‑RS delivers dependable cold‑weather starting power aboard lightweight motorcycles, utility ATVs, and competition enduro platforms. Designed as a direct replacement for legacy flooded power sources, this 12V lithium iron phosphate battery weighs just 1.3 pounds while maintaining strict OEM housing tolerances.

ENGINEERING & PERFORMANCE

Engineered with certified LiFePO4 cell composition, this component provides stable 150 Cranking Amps output across subzero startup windows without transferring parasitic weight to suspension geometries. The integrated Full BMS continuously monitors charge states, current draw, and thermal thresholds to prevent deep‑discharge damage during rigorous ride cycles. Operating directly inside established OEM electrical housings, its universal flip‑mount terminal alignment eliminates bracket modifications or wiring extensions. High‑vibration resistance and a fully sealed enclosure ensure sustained voltage delivery and complete maintenance‑free operation.

WHY RIDERS CHOOSE THIS

Riders prefer the ATZ7‑RS because its ultralight lithium construction reduces unsprung mass while preserving strong cranking torque in freezing trail conditions. The self‑jump RESTART module and active battery management system eliminate stranded riders by recovering completely discharged cells without external charging equipment. Standardized polarity layouts and precise OEM envelope geometry allow rapid swaps from failing flooded batteries without custom fabrication. This calibrated electrical profile extends seasonal storage life, protects sensitive aftermarket regulators, and sustains predictable throttle response across dirt track, backcountry, and commuting cycles.
