Antigravity SC-4 Super-Charger (Automotive/Motorcycle/Powersport) Battery Charger

Antigravity SC-4 Super-Charger | 4A Smart Battery Charger & Maintainer

Discover the Antigravity SC-4 Super-Charger: a 4-Amp multi-chemistry 6V/12V battery charger, voltage tester, and maintainer with built-in BMS wake-up reset.

The Antigravity SC-4 Super-Charger is an advanced, microchip-controlled 4-Amp battery charger and maintainer engineered for automotive, motorcycle, and powersport applications. Designed as a comprehensive garage diagnostic tool, the SC-4 seamlessly works across multiple battery chemistries, including 6V and 12V Lithium (LiFePO4) as well as 12V Lead-Acid (AGM, Gel, and Standard Wet Cell).

Unlike conventional chargers that rely on vague status LEDs, the SC-4 features a real-time LCD screen that provides instant readouts for voltage, output current, and state of charge. Packed with specialized functionalities, the unit includes an integrated Voltage Tester, a 14V/4A DC Power Supply mode to retain vehicle memory during battery swaps, and a specialized Lithium BMS Wake-Up function to revive over-discharged batteries locked in protection mode. Compact, IP65 weather-resistant, and bundled with heavy-duty clamps, eyelet harnesses, and a female cigarette lighter socket adapter, the SC-4 delivers complete maintainer functionality for seasonal storage and daily battery management.

Best Uses

1. Lithium BMS Recovery: Waking up asleep or over-discharged LiFePO4 batteries whose internal Battery Management System has triggered protection mode.
2. Seasonal & Off-Season Storage Maintenance: Long-term trickle charging and maintaining motorcycles, powersports vehicles, classic cars, lawn tractors, and seasonal equipment.
3. Memory Saver During Swaps: Powering vehicle electronics and ECU memory settings via 12V supply mode when swapping out old batteries.
4. Quick Diagnostics: On-the-spot voltage testing without needing a standalone digital multimeter.

Features

1. Lithium BMS Wake-Up / Reset Function: Sends targeted power pulses to awaken modern lithium batteries locked out by an over-discharge protection circuit.
2. Real-Time Digital LCD Display: Shows active voltage, charging amperage, battery capacity steps (20% to 100%), and mode indicators.
3. Multi-Chemistry & Dual-Voltage Support: Handles 6V/12V Lithium (LiFePO4) and 12V Lead-Acid variants (STD, AGM, GEL, FLA) for capacities up to 120Ah.
4. Integrated 12V DC Power Supply Mode: Delivers a steady 14V @ 4A output through included adapters to power small accessories or hold ECU memory.
5. Lead-Acid Recondition & Winter Modes: Built-in 16.5V recovery program for sulfated lead-acid batteries alongside weather-optimized charging algorithms.

Benefits

1. Eliminates Setup Guesswork: Clear numeric LCD readings eliminate the confusion of deciphering multi-colored flashing LEDs.
2. Revives Dead Lithium Batteries: Saves expensive LiFePO4 batteries from being discarded simply because standard chargers cannot detect voltage.
3. Universal Single-Charger Solution: Manages every battery type across motorcycles, ATVs, passenger cars, trucks, and watercraft with one unit.
4. Protects Vehicle Computer Settings: Prevents loss of radio codes, clock times, and adaptive ECU data during battery replacements.
5. Safe, Automated Maintenance: Features reverse-polarity, short-circuit, and overcharge protections so it can remain safely connected indefinitely.
