The Antigravity SC-4 Super-Charger is a multi-function 4A charger for Lithium or Lead/Acid vehicle batteries, with digital screen, built-in voltage tester. Its LCD displays the voltage and amps during charging, and a Battery Capacity Indicator gives an estimate of the battery's state of charge. The manufacturer's charge profiles cover standard flooded, AGM, gel, and LiFePO4 packs, so one unit can handle the batteries in a car, motorcycle, or powersport vehicle. Choosing a charger with chemistry-specific profiles, instead of a basic maintainer, matters because the SC-4 sets a different target voltage for each battery type. Its BMS RE-SET function can wake a lithium pack that has entered protection mode, which otherwise takes extra steps.
Because the SC-4 is a battery charger rather than a vehicle-specific part, fitment comes down to chemistry, voltage, and capacity. The manufacturer lists 3Ah ~ 120 Ah for 12V STD/AGM/LFP, 3Ah ~ 60 Ah for 6V LFP, and 12v only 3Ah ~ 32 Ah for the 12V maintenance (1A) mode. For installation, the manufacturer's manual says to select the proper battery chemistry and voltage using the "BATTERY TYPE" button before charging, then connect the positive charger clamp first, and never place the charger directly on the battery. The manufacturer's lithium battery manual also warns that lead/acid chargers and maintainers should not be used on its LiFePO4 batteries, so a lithium-capable unit is a practical choice for a mixed garage.
Yes. The manufacturer specifies support for 6V and 12V LiFePO4 (LFP) batteries, with 6V LFP capacities up to 60Ah and 12V LFP capacities up to 120Ah.
According to the manufacturer, the models differ mainly in maximum charging current: the SC-10 charges at 10 amps, the SC-4 at 4 amps, and the SC-2 at 2 amps. The SC-10 and SC-4 include special functions such as the voltage tester, power supply, and BMS reset, which the SC-2 lacks.
The manufacturer's power supply mode delivers 14V at up to 4A through the clamps, which is intended to keep the vehicle's electronics energized during a battery change. The manufacturer notes it is not intended as a high-current source.
Installation is a plug-in, select, and clamp process rather than a wiring job. Set the battery type before connecting the clamps, because the manufacturer states that the 6V and 12V options must be chosen before the charger is connected to the battery. Confirm the clamps are not touching each other, and check that the battery shows voltage, since the manufacturer notes the charger must detect voltage before it starts charging. Owners should also keep in mind that the manufacturer says sleep modes in some vehicles can prevent a charger from detecting the battery. Use the vehicle manufacturer's recommended connection point when one is specified.
