For kart racers that means one charger maintains the electric starter box battery, an onboard-start kart battery, and the tow vehicle between race weekends. Swift Karting stocks the SC-4 because dead starter batteries end race days before they begin: put it on the battery after each event and the kart lights off on the first push every time.\u003c\/p\u003e\u003ch2\u003eSmart charging made simple\u003c\/h2\u003e\u003cp\u003e\u003cimg alt=\"Antigravity SC-4 Super-Charger feature overview\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/antigravity-sc4-super-charger-INFO.jpg?v=1757954729\"\u003e\u003c\/p\u003e\u003ch2\u003eAntigravity SC-4 Super-Charger Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMulti-use versatility: works with karts, cars, trucks, motorcycles, ATVs, UTVs, RVs, tractors, boats, and more.\u003c\/li\u003e\n\u003cli\u003eMulti-chemistry support: compatible with Lithium (LiFePO4\/LFP) and Lead Acid (AGM, STD, GEL, WET, VRLA), covering both lithium kart starter boxes and lead acid units.\u003c\/li\u003e\n\u003cli\u003eMulti-voltage operation: charges 6V and 12V lithium plus 12V lead acid types.\u003c\/li\u003e\n\u003cli\u003eLCD digital display shows real-time voltage, current, and charging progress.\u003c\/li\u003e\n\u003cli\u003eTwo-button simplicity: quickly select battery type or special function in the trailer.\u003c\/li\u003e\n\u003cli\u003eBuilt-in voltage tester: check starter battery health before loading up for the track, no extra tools needed.\u003c\/li\u003e\n\u003cli\u003ePower supply mode delivers 14V at 4A to keep electronics live during battery swaps.\u003c\/li\u003e\n\u003cli\u003eBMS Re-Set function wakes lithium batteries that enter protection mode, a common fix for lithium starter box packs that sat all winter.\u003c\/li\u003e\n\u003cli\u003eRecondition mode attempts to revive sulfated or undercharged lead acid batteries.\u003c\/li\u003e\n\u003cli\u003eAutomatic Winter Mode: optimized charging in cold conditions for early and late season racing.\u003c\/li\u003e\n\u003cli\u003eCompact size: 7.8 x 3.7 x 1.8 inches with IP65 protection rating.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e110-120V AC, 50-60 Hz (US plug)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6V \/ 12V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Output Current @ 6V\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Output Current @ 12V STD\/AGM\/LFP\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBattery Capacity Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3Ah - 120Ah\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecondition Mode\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16.5V DC \/ 1.5A (lead acid only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-4°F to 104°F (-20°C to 40°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProtection Class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClass II, IP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e7.8\" x 3.7\" x 1.8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e711811704901\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAG-BC-SC-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003ciframe width=\"870\" height=\"375\" src=\"https:\/\/www.youtube.com\/embed\/oTTlHKNi4KM?si=YfKKPFC3VVcK4xr_\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\u003ch3\u003eFAQs: Antigravity SC-4 Super-Charger\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill the SC-4 charge my kart starter box battery?\u003c\/strong\u003e Yes.
