Why Lithium Iron Phosphate (LiFePO4)?

Antigravity uses lithium iron phosphate (LiFePO4) chemistry, which is the safest and most stable lithium battery technology available. LiFePO4 batteries are inherently safer than other lithium chemistries, with superior thermal stability and no risk of thermal runaway. They also deliver consistent voltage throughout discharge, excellent cold-weather performance, and exceptional cycle life.

Built-In Battery Management System (BMS):

Every Antigravity battery includes an advanced Battery Management System that protects against overcharge, over-discharge, short circuit, and thermal issues. The BMS ensures safe operation and maximizes battery lifespan by preventing conditions that could damage the cells.

Weight Savings = Performance Gains:

Reducing weight on a motorcycle has exponential performance benefits. The AG-801 saves 6-10+ lbs over a comparable lead-acid battery, and this weight reduction is high up on the bike where it matters most. The result is faster acceleration, shorter braking distances, improved handling and cornering, and even better fuel economy. For racers, every pound saved translates directly to faster lap times.

Street vs. Race Use:

• Street Use: Recommended for 600cc and larger street bikes with standard electrical loads
• Race Use: Suitable for race bikes up to 1200cc where electrical accessories are minimal
• Note: Bikes with high electrical loads (heated grips, GPS, auxiliary lights, etc.) may require a larger capacity battery

Charging & Maintenance:

Lithium batteries require different charging than lead-acid batteries. Always use a lithium-compatible charger (Antigravity SC-1, SC-4, or equivalent). The AG-801 holds its charge for up to 1 year in storage, making it perfect for seasonal bikes. No sulfation or memory effect means the battery maintains full capacity even after extended storage.
