Antigravity AT7B‑BS‑RS Lithium Battery w/ RESTART | Replaces YT7B‑BS YT9B‑BS | Fits Ducati Panigale, Yamaha Zuma, Kawasaki KLX, Suzuki DR‑Z

OVERVIEW

The Antigravity AT7B‑BS‑RS lithium battery delivers strong starting power and consistent voltage distribution for motorcycles by replacing heavy lead-acid units with a compact LiFePO4 design. This lightweight component provides reliable ignition performance for high-demand applications while significantly reducing overall system mass. It functions as a direct mechanical replacement engineered for standard case configurations across multiple vehicle families.

ENGINEERING & PERFORMANCE

Engineered with LiFePO4 chemistry, this battery produces 180 cranking amps from a 1.5-pound frame, ensuring aggressive engine ignition while protecting sensitive electronics through steady voltage delivery. A comprehensive Battery Management System guards against overcharge, deep discharge, and internal shorts, extending cycle life across rigorous operating conditions. The sealed architecture permits secure mounting in any orientation, simplifying installation within tight chassis layouts. RESTART technology enhances operational independence by enabling self-jump recovery when the unit is completely depleted.

KEY FEATURES

• LiFePO4 construction eliminates heavy lead components for reduced machine mass
• RESTART self-jump technology empowers independent recovery from full discharge events
• Output rating of 180 cranking amps guarantees rapid engine cranking under load
• Case dimensions match universal standards: 5.75 x 2.5 x 3.75 inches
• 3.3Ah true lithium capacity replaces 7Ah PbEq equivalent ratings
• Integrated BMS regulates voltage spikes and internal fault conditions

WHY RIDERS CHOOSE THIS

Riders prefer this upgrade because RESTART technology resolves stranded situations instantly, eliminating reliance on external jump starters or helper vehicles during deep discharge scenarios. Transitioning to 3.3Ah LiFePO4 construction drastically cuts unsprung weight while retaining factory-level 180 cranking amps, which sharpens throttle response and handling dynamics regardless of terrain or ride mode. The embedded BMS continuously monitors electrical health and limits current faults, safeguarding expensive electronics and extending service intervals for riders who demand long-term reliability. Durable performance in confined battery wells ensures this component is a practical solution for high-output Ducati sportbikes, Yamaha scooters, and off-road utility platforms alike.
