Antigravity U1/U1R Lithium Auto Battery | Wireless RE-START

Upgrade to the Antigravity U1/Group U1R Lithium Car Battery with built-in Wireless RE-START jump-starting. 925 Cranking Amps, ultra-lightweight, and full BMS protection.

The Antigravity U1/Group U1R Lithium Auto Battery represents the pinnacle of high-performance automotive power storage. Designed as a direct drop-in replacement for standard OEM U1 and U1R fitments, this 12-volt LiFePO4 battery delivers up to 925 Cranking Amps and 20 Ah of power while shedding up to 70% of the weight compared to traditional lead-acid equivalents (saving roughly 25 to 30 lbs).

Equipped with Antigravity’s patented RE-START Technology, you will never have to worry about getting stranded with a dead battery again. If the battery is drained (e.g., from leaving headlights or stereo equipment on), the integrated Battery Management System (BMS) automatically enters a sleep mode before total discharge, reserving just enough power to turn the engine over. Simply press the button on the included wireless keyfob remote or the top of the battery to jump-start your vehicle right from the driver's seat.

Best Uses

  1. Lightweight Sports Cars & Compact Autos: Ideal for performance applications such as the Mazda Miata or custom track builds where weight reduction directly improves acceleration and handling.
  2. UTVs & Side-by-Sides: Provides high-cranking power and shock resistance for off-road recreation.
  3. Riding Lawn Mowers & Small Tractors: Compact size combined with low self-discharge makes it perfect for seasonal farm and yard equipment.
  4. Generators & Utility Motors: Reliable starting power for emergency or field power systems.
  5. Motorsports & Track Days: Excellent for race vehicles requiring maximum cranking capability without carrying extra ballast.

Features

  1. Wireless RE-START Technology: Built-in emergency jump-starting system activated via an included keyfob remote or a top-mounted button.
  2. Advanced Integrated BMS: Features full safety circuitry to prevent over-discharge, over-charge, short-circuiting, thermal spikes, and improper cell balance.
  3. High-Power Output: Delivers 925 peak Cranking Amps and 20 Ah capacity out of a compact footprint (7.75" x 5.2" x 7.3").
  4. OEM Direct Fitment: Form-factor designed for Group U1 and U1R battery trays with included automotive SAE terminal adapters.
  5. Safe LiFePO4 Chemistry: Built using stable Lithium Iron Phosphate chemistry with non-spillable construction and zero toxic lead or acid.

Benefits

  1. Massive Weight Reduction: Drops up to 30 lbs instantly compared to lead-acid batteries, offering one of the most cost-effective performance upgrades for handling and braking.
  2. Never Stranded: Saves emergency power reserves so you can restart your car without jumper cables or external jump packs.
  3. Extended Service Life: Delivers 2x to 3x the lifecycle of standard lead-acid batteries due to intelligent battery protection.
  4. Stronger Engine Starts: High cranking power ensures faster starter turnover and reduced voltage sag during ignition.
  5. Low Self-Discharge: Retains charge significantly longer during off-season storage or periods of inactivity compared to conventional batteries.
