Antigravity Batteries ATX12-HD-RS Heavy Duty RE-START Lithium Ion Powersports Battery 480CA (MPN: AG-ATX12-HD-RS)

Drop massive amounts of dead weight from your electrical tray while unleashing explosive cranking power designed for high-displacement and high-compression motors. The Antigravity Batteries ATX12-HD-RS Heavy Duty RE-START Lithium Ion Powersports Battery 480CA is a drop-in high-performance replacement starter cell precision-crafted to maximize mechanical leverage over heavy, inefficient factory electrical configurations [MPN: AG-ATX12-HD-RS]. Generating a potent 480 cranking amps, this ultra-lightweight LiFePO4 battery safely replaces cumbersome lead-acid options to trim roughly 8 lbs (3.6 kg) off your machine, instantly sharpening handling balance, braking efficiency, and power-to-weight ratios. If an electrical accessory, lighting kit, or ignition switch is accidentally left active, the integrated Battery Management System automatically puts the cell into a sleep mode before the core energy depletes completely, reserving an isolated pocket of power to turn over your motor at the push of a wireless remote keyfob or the on-casing manual button.

Universal Battery Specification Parameters

This premium motorsports energy storage module conforms precisely to standard YTX12 dimensional envelopes, incorporating a highly versatile 4-terminal design that supports both left and right-side negative or positive configuration layouts for effortless cable routing. The rugged interior construction safely absorbs violent acceleration spikes and heavy off-road track vibrations while remaining completely sealed against liquid leakage or corrosive gassing. It can confidently maintain a full shelf charge for up to one entire year, provided the host machine is completely free of active background parasitic drains. To maintain long-term cell health and avoid terminal arcing, installers must confirm that the vehicle’s alternator or stator charging system is fully operational and regulated below a maximum continuous safety threshold of 14.8V, utilizing only dedicated LiFePO4 lithium smart chargers maintaining a regulated top-off voltage profile between 14.4V and 14.6V.

Other Applications

This drop-in high-power configuration matches the standardized dimensions of conventional YTX12, YTX12-BS, YTX14A-BS, YTZ12S, YTZ14S, and GYZ16H lead-acid battery footprint locations. It acts as the ultimate performance upgrade for a wide spectrum of metric cruiser motorcycles, sport touring bikes, utility UTV side-by-sides, full-size sport ATVs, snowmobiles, and personal watercraft requiring massive initial torque to push past high internal engine compression. Additionally, its exceptional power-to-weight ratio allows it to safely crank high-performance racing car applications (such as sports cars or track day vehicles) where extreme weight reduction in a compact size format is required. It can be securely mounted in any orientation layout.

CRITICAL INSTALLATION AND SAFETY NOTES: Always execute proper terminal separation sequences by disconnecting the ground negative cable first during removal and connecting the ground negative cable last during final installation to avoid hazardous chassis shorts. Never utilize traditional workshop lead-acid battery chargers or tenders that feature an automatic or manual high-voltage desulfation pulse mode, as this process will instantly destroy the internal lithium circuit and void all factory warranties. Ensure the battery module is snugly secured in your machine's tray using the included adhesive-backed high-density foam spacers to eliminate physical rattling, and check that all terminal fastening bolts are fully torque-seated to prevent intermittent cranking failures.
