Antigravity H6/Group 48 Lithium Car Battery

Antigravity H6 / Group 48 Lithium Car Battery | Wireless Re-Start

Upgrade to the Antigravity H6 / Group 48 Lithium Car Battery. Features wireless Re-Start jump-starting, built-in BMS, up to 1800 CA, and massive weight savings.

The Antigravity H6 / Group 48 Lithium Car Battery delivers advanced starter battery technology directly to high-performance, track, and daily-driven vehicles. Built using safe LiFePO4 (Lithium Iron Phosphate) chemistry, this battery replaces standard heavy lead-acid H6/Group 48 batteries with an exact drop-in fitment.

Engineered with Antigravity’s exclusive RE-START technology, you never have to worry about getting stranded with a dead battery again. If the battery drains due to sitting or active parasitic loads, it automatically enters a protective sleep mode before full discharge. With the press of the included wireless keyfob remote, you can activate the built-in jump-starting system from the comfort of your seat without opening the hood. Weighing up to 70% less than conventional lead-acid options, it sheds 30–40 lbs of unsprung weight to improve acceleration, braking distance, and cornering balance.

Best Uses

1. Performance & Track Cars: Lightweight power reduction for sports cars, track-day builds, and supercars where losing vehicle mass directly improves lap times and handling.
2. Daily Drivers & European Vehicles: Ideal OEM replacement for sports coupes, sedans, and SUVs utilizing Group 48/H6 battery fitment standards.
3. Seasonal & Weekend Vehicles: Perfect for vehicles stored for extended periods, preventing full discharge damage thanks to built-in sleep modes and low self-discharge rates.
4. High-Crank Motors: Recommended for tuned and high-compression engines requiring up to 1800 Cranking Amps for quick startup reliability.

Features

1. Wireless RE-START Technology: Built-in emergency jump-starting activated remotely via keyfob without lifting the vehicle hood.
2. Integrated Battery Management System (BMS): Onboard smart circuit board providing over-charge, over-discharge, thermal protection, short-circuit protection, and cell balancing.
3. Exact OEM Drop-in Fitment: Standard Group 48 / H6 casing dimensions (10.75" x 7" x 7.5") for direct installation using factory battery trays and tie-downs.
4. Safe LiFePO4 Chemistry: Uses Lithium Iron Phosphate technology, eliminating hazardous liquid acids, toxic heavy metals, and dangerous off-gassing.
5. Multiple Capacity Options: Available in 24Ah, 30Ah, 40Ah, and 60Ah configurations delivering up to 1800 Cranking Amps.

Benefits

1. Massive Weight Reduction: Saves up to 40 lbs compared to traditional lead-acid batteries, delivering an immediate performance upgrade in vehicle dynamics.
2. No Stranded Dead Batteries: Automatically preserves enough power in reserve mode to start the motor when triggered, eliminating the need for jumper cables or roadside calls.
3. Longer Service Life: Delivers 2x to 3x the lifecycle of standard AGM or lead-acid batteries when properly maintained.
4. Faster Engine Starts: Higher, stable voltage output under cranking conditions produces quicker, crisper engine turnover.
5. Maintenance & Acid-Free: Non-spillable solid design that withstands high shock and vibration without leaking damaging acids onto your chassis.
