SC-4 Antigravity Super-Charger Battery Charger

The Antigravity SC-4 Super-Charger is an advanced, multi-function 4-Amp battery charger and maintainer designed for all your motorcycle, automotive, and powersport needs. Compatible with 12V Lead/Acid (AGM, STD, GEL), 12V Lithium (LiFePO4), and 6V Lithium batteries, this intelligent unit goes far beyond standard trickle charging.

Unlike traditional chargers with basic LED dummy lights, the SC-4 features a large, backlit LCD screen that displays real-time voltage, charging amps, and battery capacity. It serves as an all-in-one garage tool with a built-in voltage tester, a BMS "Wake-Up" function to revive sleeping lithium batteries, and a 4-Amp Power Supply mode to keep vehicle electronics energized during battery swaps. Intelligent microchip technology actively monitors your battery to prevent overcharging, short-circuiting, and reverse polarity, ensuring safe, long-term battery maintenance.

Features:

• 4-Amp Charging: Delivers a safe, steady 4-Amp maximum output for 12V batteries, perfect for charging and maintaining capacities ranging from 3Ah to 120Ah.

• Multi-Chemistry: Safely charges and maintains 12V Lead/Acid (AGM, Standard, Gel), 12V Lithium (LiFePO4), and 6V Lithium batteries. (Note: Not for 6V Lead/Acid).

• LCD Digital Display: Provides real-time visual data including exact voltage, amperage, charging level (20-100%), and selected battery mode.

• BMS Wake-Up: Specialized function safely resets and revives Lithium batteries that have tripped into low-voltage Protection Mode.

• Power Supply Mode: Functions as a 12~14V/4A power supply to maintain vehicle ECU memory during battery swaps or to power 12V accessories using the included adapter.

• Built-In Voltage Tester: Allows you to instantly check battery health without needing a separate multimeter.

• Advanced Diagnostics: Includes a Recondition Mode for recovering sulfated Lead/Acid batteries and an automatic Winter Mode for optimal cold-weather charging.

What's in the Box:

• 1x Antigravity SC-4 Super-Charger (with attached AC cable and SAE cable)

• 1x Alligator Clamps Accessory

• 1x Ring Terminal Pigtail Accessory

• 1x Female Cigarette Lighter Adapter

• User Manual

Fitment Notes:

• Universal Application: Ideal for modern motorcycles, dirt bikes, ATVs, UTVs, cars, trucks, and lawn tractors.

• Capacity Range: Suitable for 12V batteries ranging from 3Ah to 120Ah, and 6V Lithium batteries ranging from 3Ah to 60Ah.

• The SAE Advantage: Unlike many popular battery charger brands that force you to use their proprietary cable connectors, Antigravity utilizes an industry-standard 2-pin SAE connector. This means if your motorcycle already has a standard SAE pigtail installed for heated gear or an older charger, you can plug the SC-4 directly into it without having to rewire your bike.

• Lithium Wake-Up: If you accidentally leave the key on and drain a modern lithium motorcycle battery, its internal Battery Management System (BMS) will shut the battery down entirely to prevent permanent cell damage. Standard lead-acid chargers won't recognize that the battery is even connected and will refuse to charge it. The SC-4’s specific BMS Wake-Up feature bypasses this safety lock to carefully ping the battery and initiate the charging sequence.
