Antigravity Extreme Power Series XPS V-10 Lithium Ion Motorcycle Battery Left Side Negative (MPN: AG-V10-L)

Drop a substantial amount of dead weight from your chassis tray while unleashing unmatched engine cranking throughput. The Antigravity Extreme Power Series XPS V-10 Lithium Ion Motorcycle Battery Left Side Negative is an ultra-compact, high-performance starter cell precision-crafted to maximize mechanical leverage over heavy, inefficient factory electrical configurations [MPN: AG-V10-L]. Pumping out an incredible 680 cranking amps within a miniature package, this featherweight LiFePO4 battery replaces cumbersome lead-acid variants to drop up to 14 lbs (6.4 kg) off a motorcycle or 32 lbs (14.5 kg) off a dedicated race car chassis. By choosing to bypass the internal RE-START reserve electronics found on standard street modules, this specialized racing battery maximizes its active cell mass to deliver explosive cranking currents capable of turning over high-compression V-Twin and race-use engine builds with absolute ease.

Universal Battery Specification Parameters

This premium competition-grade energy module operates within a standardized YTZ10 envelope footprint, incorporating heavy-duty top terminals featuring an unbreakable, all-brass block layout for high-conductivity connections. The rugged interior construction safely absorbs violent acceleration spikes and heavy off-road track vibrations while remaining completely sealed against dangerous liquid leaks or corrosive gassing. It can confidently maintain a full shelf charge for up to one entire year, provided the host racing machine is completely isolated from background parasitic draws. To maximize long-term mechanical reliability and avoid terminal arcing, installers must confirm that the charging system is properly regulated and outputting a stable charge configuration below a maximum safety threshold of 14.8V.

Other Applications

This drop-in high-performance configuration matches the standardized dimensions of conventional YTZ10 battery trays requiring a left-side negative terminal orientation (critical for clean cable routing across specific model subframes). It is an ideal starting battery choice for large custom motors up to 135 cubic inches (2212cc) as well as race-use V8 engines where weight reduction is critical. Note that this performance module is strictly not intended for use in standard passenger cars, consumer street automobiles, or daily driver touring vehicles with constant accessory draws.

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. Do not use standard manual or automatic lead-acid battery chargers or tenders that feature an automatic desulfation pulse mode, as this high-voltage process will irreparably damage the internal lithium chemistry and void the manufacturer warranty. Use only a dedicated LiFePO4 lithium smart charger maintaining a regulated voltage profile between 14.4V and 14.6V, and always make sure that all mounting brackets or high-density foam spacers are firmly tightened to prevent physical module shifting under track conditions.
