Antigravity H6/Group 48 Lithium Car Battery w/Re-Start

Antigravity H6 / Group 48 Lithium Car Battery with RE-START Tech

Upgrade to the Antigravity H6 / Group 48 Lithium Car Battery. Ultra-lightweight design with built-in wireless RE-START jump-starting and advanced BMS.

The Antigravity H6 / Group 48 Lithium Automotive Battery is a direct drop-in OEM replacement engineered for performance enthusiasts, track-day racers, and everyday drivers seeking massive weight savings and total power reliability. Encased in a standard BCI Group 48 / H6 housing, this battery replaces heavy lead-acid or AGM batteries while shaving off up to 40 lbs from your vehicle’s front end or trunk.

Equipped with Antigravity's patented RE-START Technology, you will never worry about getting stranded by a drained battery again. If the battery voltage drops below a safe starting threshold, it automatically puts itself into a protected sleep mode, saving enough power to crank your engine. Simply press the included wireless remote key fob (or the manual button on top of the case), start your car, and drive off. Inside, safe LiFePO4 (Lithium Iron Phosphate) chemistry pairs with a full Battery Management System (BMS) to actively balance cells and protect against over-charge, over-discharge, thermal issues, and short circuits.

Best Uses

1. Track & Motorsport Performance: Ideal for sports cars (such as Porsche, Audi, BMW, Corvette, and Mustang) where removing 30–40 lbs improves cornering balance, braking distance, and power-to-weight ratios.
2. High-Horsepower Street Builds: Easily cranks over high-compression, large-displacement engines up to 900+ horsepower that demand high initial starting current.
3. Seasonal & Weekend Vehicles: Excellent for show cars, weekend toys, or seasonal drivers that sit for extended periods, thanks to lithium's extremely low self-discharge rate.
4. Direct OEM Lead-Acid Replacement: A plug-and-play upgrade for any passenger vehicle, light truck, or SUV requiring a standard BCI Group 48 / H6 battery footprint.

Features

1. Wireless RE-START Remote Jump-Starting: Features built-in wireless jump-starting activated via a key fob remote, allowing you to wake up a dead battery without opening the hood.
2. Integrated Battery Management System (BMS): Microprocessor-controlled BMS protects against over-charge, over-discharge, short-circuiting, thermal spikes, and includes automatic cell balancing.
3. Exact OEM Group 48 / H6 Fitment: Designed in the standard 10.75" x 7" x 7.5" case dimensions for a direct bolt-in fitment using factory mounts and cables.
4. Massive Cranking Power: Delivers high output (up to 1,500–1,800 Cranking Amps depending on Ah capacity option) for fast, sharp engine turns.
5. Safe LiFePO4 Chemistry: Built using stable Lithium Iron Phosphate cell technology, eliminating acid spills, off-gassing, and heavy toxic metals.

Benefits

1. Instant Weight Reduction: Weighs up to 70% less than standard lead-acid batteries, immediately shaving 30 to 40 lbs off your vehicle for enhanced handling and performance.
2. Zero-Strand Peace of Mind: Eliminates the need for external jumper cables, jump packs, or roadside assistance if your lights or accessories drain the battery.
3. Longer Service Life: Delivers 2x to 3x the cycle life of traditional AGM or lead-acid batteries, offering up to 7–9 years of operational lifespan.
4. Faster Engine Starts & Better Charging: Provides higher nominal voltage during cranking for faster starts and recharges up to twice as fast as lead-acid options.
5. Superior Storage Retention: Features an extremely low self-discharge rate, allowing the battery to hold a charge for months during storage without going flat.
