Antigravity Batteries SC-4 4A Smart Charger for 6V/12V LiFePO4 & 12V Lead‑Acid — LCD & BMS Reset

The Antigravity SC-4 Super-Charger is a 4‑amp, wall‑powered smart charger and maintainer engineered to safely charge, diagnose, and maintain 6V/12V LiFePO4 and 12V lead‑acid batteries with an easy two‑button interface.

The SC-4 combines precise charging electronics, a clear LCD readout, and practical service tools into a single compact unit for garages, workshops, and seasonal storage. It handles multiple chemistries—6V and 12V lithium iron phosphate plus a broad range of 12V lead‑acid types—and adds diagnostics like voltage testing and a BMS wake/reset routine for lithium packs. With accessory cables and automotive connections included, the charger adapts to motorcycles, cars, ATVs, UTVs, boats, RVs, and lawn equipment without needing a separate multimeter or power supply.

How does the SC-4 handle different battery chemistries?

The SC-4 automatically selects appropriate charging profiles for supported chemistries and provides targeted maintenance modes to preserve battery life. Its onboard microchip controls current and voltage, while specialized functions support deeply discharged lead‑acid batteries and lithium packs with protective BMS.

• Compatible with 6V and 12V LiFePO4 (LFP) batteries.
• Works with 12V lead‑acid types: AGM, FLA, GEL, WET, SLA, VRLA.
• Automatic mode selection prevents overcharging and reduces maintenance needs.

What diagnostics and service features are included?

The large LCD shows voltage, charging current, and battery status so you can track progress at a glance. Built‑in tools let you test voltage, wake or reset a lithium BMS, and run a reconditioning routine to help recover certain discharged lead‑acid batteries.

• Real‑time voltage and current readouts on the digital display.
• Voltage tester removes the need for a separate multimeter for basic checks.
• LiBMS wake/reset to revive batteries in protection mode (where applicable).
• Recondition function designed to assist with deeply discharged lead‑acid units.

How does it fit into workshop and vehicle workflows?

The SC-4 is designed for frequent use: a wall‑powered design supplies steady charge current and a Power Supply mode keeps vehicle electronics alive during battery swaps. The simple two‑button interface and industry‑standard SAE connector let technicians and hobbyists connect quickly and safely.

• 4A charging and a dedicated 4A Power Supply mode for on‑vehicle electronics.
• Includes clamps, an SAE pigtail, and a cigarette lighter adapter for flexible hookups.
• Automatic safety protections guard against reverse polarity, short circuits, and overheating.

What safety and seasonal features should I expect?

The charger includes automatic protections and a Winter Mode to adapt charging behavior in colder conditions, helping maintain batteries during long storage periods. Its compact, durable build and clear status feedback allow confident use in garages and workshops.

• Automatic temperature‑aware Winter Mode for cold charging conditions.
• Built‑in protections against reverse polarity and other common issues.
• Durable enclosure and simple controls for repeated shop use.

Who is this for: The Antigravity SC-4 is aimed at vehicle owners, powersports enthusiasts, and workshop technicians who need a reliable, multi‑chemistry charger and maintainer with diagnostic capability. If you manage motorcycles, ATVs, boats, RVs, lawn equipment, or cars and want a single, easy‑to‑use device for charging, testing, and maintaining batteries—especially LiFePO4 and various 12V lead‑acid types—the SC-4 provides a compact, professional solution without extra tools.
