Antigravity AG-801 Small Case Lithium Motorcycle Dirt Bike ATV Battery

The Antigravity AG-801 Small Case Lithium Battery is a specialized power source built specifically for race vehicles, dirt bikes, ATVs, and custom motorcycle projects. It is designed to solve the problem of excessive weight and tight spatial constraints in custom setups, offering a lightweight alternative where traditional power cells cannot fit.

Its primary advantage lies in the power-to-weight ratio. Weighing only 1.56 lbs, it delivers 240 Cranking Amps of starting power. This enables high-performance starting capabilities while significantly shedding excess pounds from your build. Additionally, the compact casing measures 4.375 by 2.37 by 3.75 inches, allowing builders to tuck the battery away in tight locations on custom frames.

However, this specialized battery demands strict maintenance protocols. It does not include an internal Battery Management System (BMS) and cannot handle parasitic drain. Buyers must use a dedicated lithium charger and properly maintain the unit, as improper use or standard street vehicle demands can permanently damage it.

Verdict: The Antigravity AG-801 is an outstanding choice for track enthusiasts and custom builders who need high cranking power in a miniature, ultra-light package. Everyday riders who need universal fitment or built-in electronic protections should look at standard street-oriented alternatives like the brand RE-START series instead.

• Weight: 1.56 lbs
• Cranking Amps: 240 CA
• Dimensions: 4.375 x 2.37 x 3.75 inches
• Battery Type: Small case lithium
• Intended Use: Race, performance, and custom applications

A great fit if you:

• Are building a race vehicle, dirt bike, or custom motorcycle with severe space limits
• Need to minimize vehicle weight without sacrificing 240 Cranking Amps of starting power
• Understand proper lithium battery care and already use a compatible lithium charger

Consider something else if you:

• Drive a typical everyday street vehicle with parasitic electrical drain
• Need a battery with an integrated Battery Management System (BMS) or built-in protections

Can I use this as a replacement battery in an everyday street bike?
No. This battery is intended only for race, performance, and custom applications, and is not designed for everyday street vehicles or setups with parasitic drain.

Does this battery include a Battery Management System (BMS)?
No, it does not have an internal BMS. Users must ensure proper installation, routine maintenance, and correct charging to prevent permanent damage.

What type of charger is required?
You must use only a compatible lithium charger. Standard non-lithium chargers or improper maintenance can ruin the battery.
