Antigravity H5/Group 47 Lithium Car Battery w/Re-Start

Antigravity H5/Group 47 Lithium Car Battery w/ Wireless RE-START

Upgrade to the Antigravity H5/Group 47 Lithium Car Battery. Save up to 40 lbs, get up to 1500 CA, and never get stranded with built-in wireless RE-START® technology.

The Antigravity H5 / Group 47 Lithium Car Battery represents a massive technological leap over standard lead-acid and AGM batteries. Designed as a direct drop-in replacement for BCI Group 47 / DIN H5 battery trays, this ultra-lightweight Lithium-Iron Phosphate ($\text{LiFePO}_4$) battery reduces vehicle weight by up to 40 lbs while delivering up to three times the cranking power of conventional batteries.

Equipped with Antigravity’s patented RE-START® Wireless Technology, you will never worry about a dead battery leaving you stranded. If vehicle lights or accessories accidentally drain the battery, the integrated Battery Management System (BMS) automatically puts the battery into a protective sleep mode before it dies. It retains just enough reserve energy to start your engine—allowing you to press the included wireless key fob, jump-start the car from the safety of the driver's seat without opening the hood, and drive away.

Featuring an advanced built-in BMS that manages cell balancing, over-charge, over-discharge, short-circuit, and thermal protections, the Antigravity H5 offers up to 2–3 times the lifespan of a lead-acid battery.

Best Uses

1. Track & Motorsport Vehicles: Ideal for race cars, track-day builds, and auto-cross cars where dropping 30–40 lbs of high-front/rear unsprung weight dramatically improves cornering, acceleration, and braking performance.
2. High-Performance Sports Cars & Supercars: A popular OEM fitment upgrade for European sports cars and performance vehicles (e.g., Porsche, Audi, BMW, Volkswagen, Corvette, and Lotus).
3. Daily Drivers & Street Rods: Excellent for performance daily drivers that sit parked for extended periods or vehicles prone to parasitic draw.
4. Custom & Weight-Sensitive Builds: Perfect for builders looking for the most cost-effective "dollars-per-pound" weight reduction on the market.

Features

1. Wireless RE-START® Technology: World’s first battery featuring built-in, wireless remote jump-starting via an included key fob or physical button on top of the battery.
2. Integrated Battery Management System (BMS): Microprocessor-controlled BMS protects against over-charging, over-discharging, short circuits, extreme temperatures, and handles automatic cell balancing.
3. Direct OEM Fitment (Group 47 / H5 Case): Direct drop-in sizing () designed to fit directly into factory battery trays and utilize stock mounting hardware and terminals.
4. Safe  Chemistry: Utilizes stable, non-combustible Lithium Iron Phosphate chemistry for maximum thermal safety and long-term reliability.
5. Multiple Amp-Hour Options: Offered in various capacity configurations (such as 24Ah, 30Ah, and 40Ah) providing up to 1500 Cranking Amps.

Benefits

1. Massive Weight Reduction: Saves up to 40 lbs compared to heavy lead-acid/AGM counterparts (70% weight reduction), directly enhancing vehicle handling, acceleration, and fuel economy.
2. No More Getting Stranded: The smart BMS puts the battery to sleep before total discharge, guaranteeing you always have reserve power to start the vehicle.
3. Superior Engine Cranking Power: Delivers high cranking amperage (up to 1500 CA) to turn over high-compression and high-horsepower engines up to 900+ HP with ease.
4. Significantly Longer Lifespan: Offers 2x to 3x the service life of traditional lead-acid batteries with ultra-low self-discharge rates during storage.
5. Cost-Effective Performance Upgrade: Provides one of the cheapest ways to shed significant weight off a car compared to high-cost alternatives like carbon fiber or titanium components.
