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

Antigravity H8/Group 49 Lithium Car Battery w/ Re-Start | Lightweight LiFePO4

Upgrade to the Antigravity H8 / Group 49 Lithium Car Battery. Save up to 40 lbs, double your cranking power, and never get stranded with wireless RE-START technology.

The Antigravity H8 / Group 49 Lithium Car Battery is an OEM drop-in replacement designed for modern high-performance, luxury, and exotic vehicles. Built on safe and stable LiFePO4 chemistry, it combines serious weight reduction with up to double the starting power of traditional lead-acid or AGM batteries.

Equipped with Antigravity’s RE-START Technology, the battery automatically monitors voltage levels and puts itself into a protected sleep state before being completely drained by parasitic loads or left-on accessories. If the battery goes to sleep, simply press the button on the included wireless key fob to jump-start the car from the safety of the driver’s seat—no jumper cables, power banks, or hood opening required. Managed by an integrated, full-featured Battery Management System (BMS), it ensures maximum thermal safety, cell balancing, and long service life.

Best Uses

1. High-Performance & Track Vehicles: Eliminates 30 to 40+ lbs of sprung mass from the vehicle without sacrificing start-up reliability.
2. Exotic & Luxury Sports Cars: Direct drop-in fit for European and American performance platforms, including Porsche, BMW, Audi, Mercedes-Benz, Ferrari, and Dodge Vipers/Chargers.
3. Show & Weekend Cars: Low self-discharge rate makes it suitable for stored or infrequently driven vehicles subject to parasitic battery drain.
4. High-Horsepower Engines: High cranking amp delivery easily turns over large displacement or high-compression engines (up to 900+ HP).

Features

1. Wireless RE-START Remote Jump-Starting: Features built-in reserve power activated via the included wireless remote key fob or top-mounted button.
2. Integrated Battery Management System (BMS): Onboard digital BMS protects against over-charge, over-discharge, short-circuits, and extreme temperatures while managing active cell balancing.
3. Exact OEM H8 / Group 49 Case Size: Standardized dimensions () for plug-and-play installation into factory battery trays.
4. Massive Power Output: Delivers  (60Ah model) to  (80Ah model) for quick, reliable engine turnover.
5. Safe LiFePO4 Chemistry: Uses stable Lithium Iron Phosphate cell technology that contains no toxic heavy metals or free liquids.

Benefits

1. Instant Weight Reduction: Drops up to 40 lbs compared to lead-acid batteries, improving vehicle handling, braking performance, and acceleration.
2. Eliminates Getting Stranded: Built-in low-voltage cut-off preserves enough energy to restart the vehicle if lights or accessories drain the battery.
3.  Longer Service Life: Lasts significantly longer than standard AGM batteries due to thermal management and protection against deep-discharge damage.
4. Faster Engine Starts: Higher maintained voltage during starting provides quicker engine turnover and stronger ignition current.
5. Superior Shock & Vibration Resistance: Solid-state lithium architecture handles high-vibration automotive and motorsports environments better than lead plates.
