The Antigravity SC-4 is a 4 amp multi-function charger for lithium (LiFePO4) and lead/acid batteries up to 120Ah, with the feature that matters most for lithium owners: BMS wake-up. When a lithium battery's management system goes into protection mode, most chargers see zero volts at the terminals and refuse to charge; the SC-4 sends a pulse to wake the BMS and then charges normally.

It also works as a voltage tester and a power supply, so vehicle settings survive a battery swap, and the 4 amp rate charges larger batteries twice as fast as the SC-2.

Features

• Charges 6V and 12V lithium (LiFePO4) and 12V lead/acid batteries of all types (AGM, GEL, STD, WET, FLA, VRLA)
• 4 amp output for batteries up to 120Ah
• BMS wake-up function recovers lithium batteries that have gone into protection sleep
• First-of-its-kind onboard voltage tester, no separate multimeter needed
• Power supply mode delivers up to 4A at 12-14VDC to keep vehicle settings alive during battery swaps
• Large LCD display with real-time voltage, current, and capacity
• Automatic winter mode and lead/acid recondition function
• Remembers the last setting used and resumes after a power interruption

What's Included

• SC-4 Super-Charger
• Battery clamp lead (SAE interchangeable)
• Ring terminal pigtail lead (SAE interchangeable)
• Female cig-lighter adapter for the power supply function

Installation Notes

• Select the lithium setting before connecting an Antigravity lithium battery.
• The recondition mode is for lead/acid batteries only; never run desulfation or recondition cycles on a lithium battery.
• Antigravity RE-START batteries can wake their own BMS with the on-case button; the SC-4's wake-up function covers non-RE-START lithium batteries.
• The power supply mode is not for ECU tuning applications that require higher current.
