Antigravity SC-4 Super-Charger | 4-Amp Smart Lithium & Lead-Acid Battery Charger

The Antigravity SC-4 Super-Charger is a compact 4-amp smart charging solution for lithium and lead acid batteries up to 120 Ah. For kart racers that means one charger maintains the electric starter box battery, an onboard-start kart battery, and the tow vehicle between race weekends. Swift Karting stocks the SC-4 because dead starter batteries end race days before they begin: put it on the battery after each event and the kart lights off on the first push every time.

FAQs: Antigravity SC-4 Super-Charger

Will the SC-4 charge my kart starter box battery? Yes. It supports lithium (LiFePO4/LFP) and lead acid chemistries from 3Ah to 120Ah, which covers the batteries used in electric kart starter boxes and onboard-start karts.

Is the SC-4 safe to leave connected long-term? Yes. It has automatic maintenance mode and built-in safety protections, so you can leave it on the starter battery between race weekends without worry.

How is the SC-4 different from the SC-10? The SC-4 provides 4A charging, best for small to mid-size batteries like kart starter packs. The SC-10 offers faster 10A charging for larger-capacity batteries.

Can I use it for battery swaps? Absolutely. The 4A power supply function keeps vehicle electronics energized so you do not lose settings during battery changes.

Keep your kart starter batteries healthy and race ready with the Antigravity SC-4 Super-Charger, available from Swift Karting.
