Antigravity H8/Group 49 Lithium Car Battery w/Re-Start

Antigravity H8/Group 49 Lithium Car Battery w/ RE-START | Lightweight Power

Upgrade to the Antigravity H8/Group 49 Lithium Battery. Drop up to 40 lbs, get up to 2000 CA, and never get stranded with wireless remote RE-START jump-starting.

The Antigravity H8/Group 49 Lithium Car Battery is an ultra-lightweight, high-performance power solution designed as a direct OEM-fit replacement for standard lead-acid or AGM Group 49 batteries. Engineered with safe, long-lasting LiFePO4 (Lithium Iron Phosphate) chemistry, this battery delivers massive cranking power—up to 2,000 CA depending on the Ah configuration—while shaving up to 40 lbs off your vehicle’s total weight.

What truly sets the Antigravity RE-START line apart is its revolutionary, intelligent Battery Management System (BMS) equipped with wireless RE-START technology. If your battery drops to a dangerously low voltage state—such as from leaving lights on or letting the vehicle sit during winter storage—the internal BMS puts the battery to sleep before it drains fully. When you are ready to start the car, simply press the button on the included wireless key fob, start the engine, and drive away without ever popping the hood or carrying an external jump pack.

Best Uses

1. High-Performance & Sports Cars: Perfect for exotic and sports applications (e.g., Porsche, BMW, Audi, Mercedes, Ferrari) where removing weight over the front or rear axle dramatically improves handling dynamics, braking distances, and acceleration.
2. Track Days & Racing Applications: Ideal for motorsport platforms seeking maximum power-to-weight ratios without sacrificing electrical system capacity or reliable engine starting.
3. Seasonal & Weekend Vehicles: Excellent for vehicles that sit in garage storage for long stretches, thanks to extremely low self-discharge rates and automatic sleep protection.
4. High-Horsepower Engine Builds: Built to effortlessly turn over high-compression, high-displacement, or high-horsepower builds up to and over 900 HP.

Features

1. Built-In Wireless RE-START Technology: Includes a wireless remote key fob that lets you activate the battery's reserve power from the safety of your driver's seat.
2. Full Battery Management System (BMS): Microprocessor-controlled safety circuitry protects against over-charging, over-discharging, short circuits, extreme heat, and cell imbalance.
3. Exact OEM Group 49 Fitment: Standardized case size () for a seamless drop-in replacement with standard automotive terminals.
4. Massive Cranking Amps: Delivers up to 1,800 CA (60Ah model) or ~2,000 CA (80Ah model) to fire up demanding high-performance engines instantly.
5. LiFePO4 Chemistry: Built using safe, stable Lithium Iron Phosphate cell technology for optimal power delivery and safety.

Benefits

1. Massive Weight Reduction: Saves up to 40 lbs (up to 70% lighter) compared to a traditional lead-acid/AGM battery, improving agility, cornering, and acceleration.
2. Eliminates Getting Stranded: Sleep mode preserves enough emergency power to jump-start your vehicle at the press of a key fob button.
3. 2x to 3x Longer Lifespan: Offers significantly more charge cycles than lead-acid batteries, providing years of consistent performance.
4. Low Self-Discharge: Retains charge far longer during downtime, making it reliable for infrequently driven weekend cars.
5. Stronger, Faster Engine Cranking: Delivers a higher, more consistent voltage during starting, leading to faster ignition turns and reduced strain on starter motors.
