It exists for builds where the battery needs to disappear: kickstart-only Harley choppers and bobbers running lights and ignition, race bikes chasing every ounce, and total-loss setups.\u003c\/p\u003e\u003cp\u003eIt hides inside a small battery box or frame tube and mounts in any orientation.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSmallest, lightest battery in the Antigravity line\u003c\/li\u003e\n\u003cli\u003eBuilt for kickstart-only V-twins, race, and total-loss applications\u003c\/li\u003e\n\u003cli\u003eMounts in any orientation; vibration resistant\u003c\/li\u003e\n\u003cli\u003eLarge all-brass terminal design\u003c\/li\u003e\n\u003cli\u003eLiFePO4 chemistry; holds a charge up to a year without parasitic drains\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAG-401 lithium battery\u003c\/li\u003e\n\u003cli\u003eAdhesive-backed installation foam\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSmall Case batteries use balance charging without an onboard BMS; Antigravity positions them for race, off-road, and custom applications.\u003c\/li\u003e\n\u003cli\u003eOn classic bikes from the mid-1980s and earlier, update the charging system to a modern voltage regulator before running a lithium battery; a failing regulator can overcharge and damage it.\u003c\/li\u003e\n\u003cli\u003eNot intended for electric-start V-twins; step up through the 8, 12, and 16-cell Small Case sizes as cranking demand grows.\u003c\/li\u003e\n\u003cli\u003eCharge only with a lithium-compatible (LiFePO4) charger such as the Antigravity SC-2 or SC-4 Super-Charger.
