(Please note if you use older bikes from the mid 1990's and earlier you must update the charging systems to a modern voltage regulator. Damaged voltage regulators can over charge and damage lithium batteries)

Product Description

The Antigravity Batteries AG1201 is an extremely versatile high power and lightweight Lithium Motorcycle/Motorsports battery. It has the capability for large weight reduction in the most compact size in lithium batteries in its class.  It has 360 Cranking Amps yet is only 4.50″ Length x 3.25″ Depth and 4.25″ height (to the top of the terminals). This battery is a great choice for those seeking very high power in a compact battery. It can replace the typical 12 Ah Lead/Acid battery with a weight saving of up to 7 pounds while offering much more cranking power. This battery is best used for applications where extreme weight loss and ultra compact size are desired.


Best uses
  • Capable of every day use in bikes up to 1100cc   (For more capacity and power use the Antigravity AG1601)
  • Race and Track Day use 1500cc
  • Custom builds up to 1200cc.  (If using a high-performance motor use the Antigravity AG1601)
  • 4 Cylinder Race Cars up to 1800cc

Please note

You MUST only charge our lithium batteries with a lithium specific battery charger, (such as the Optimate battery chargers offered on this website) the use of any other type of battery charger is likely to damage the battery and invalidate the guarantee.
