Antigravity Batteries ATZ7-RS RE-START Lithium Ion Powersports Battery 150CA (MPN: AG-ATZ7-RS)

Drop up to 70% of dead weight from your vehicle's engine bay while ensuring you never get stranded by an accidental accessory power drain. The Antigravity Batteries ATZ7-RS RE-START Lithium Ion Powersports Battery 150CA is a drop-in high-performance replacement starter cell precision-crafted to maximize mechanical leverage over heavy, inefficient factory electrical setups [MPN: AG-ATZ7-RS]. Generating a potent 150 cranking amps, this ultra-lightweight LiFePO4 battery safely replaces heavy lead-acid options to trim critical pounds off your machine's chassis, instantly improving handling balance, braking efficiency, and acceleration response. If an electrical accessory or ignition switch is accidentally left running, 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 built-in button.

Universal Battery Specification Parameters

This premium motorsports energy solution conforms precisely to standard YTZ7 case form factors, incorporating a 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 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 draws. To maintain long-term reliability and avoid terminal arcing, installers must confirm that their alternator charging circuit or stator assembly is fully operational and regulated below a maximum safety threshold of 14.8V, using 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 YTZ7S, YTZ5S, YTZ8V, YTX4L-BS, YTX5L-BS, and YTX7L-BS lead-acid battery footprint locations. It acts as the ultimate performance upgrade for roughly 90% of modern electric-start off-road dirt bikes, racing dual-sports, lightweight sport ATVs, commuter scooters, and high-displacement single-cylinder machines requiring maximum initial torque to push past high internal engine compression. Can be securely mounted in any orientation layout.

CRITICAL INSTALLATION AND SAFETY NOTES: Always disconnect the negative grounding lead first during stock battery removal and connect the negative grounding terminal last during final installation to eliminate the risk of accidental frame 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.
