Antigravity Batteries

Small Case Lithium Battery

The AG-401 battery, at a minuscule 4.25″ Length x 1.25″ Depth and 3.75″ Height (to the top of the terminals), offers extreme power in the most compact size in Lithium Motorsport batteries. The AG-401 is best used for Performance applications where extreme weight loss and ultra-compact size are desired. Can start inline 4-Cylinder motors up to 600cc for race use, or up to 250cc for everyday street use in scooters. This battery is also a favorite of custom builders who want the smallest battery to tuck out of the way.

Best Uses

• Capable of everyday use in bikes up to 250cc.
• Race use for Enduro and MX electric start bikes up to 450cc. (If you have a 250cc 2-stroke you will need to use the Antigravity Battery AG-801)
• Race and Track Day use in inline 4 cylinder 600cc sportbikes (Honda CBR600 rider should use the Antigravity Battery: AG-801).
• Custom builds like cafe racers or small bore customs up to 350cc. (Please note if you use older classic bikes from the mid-1980s and earlier you should update the charging systems to a modern voltage regulator; a damaged voltage regulator can overcharge the battery and damage it.)

The folks over at Prism Supply Co have come up with the perfect battery tray for the Antigravity 4 cell Battery. You can find it here!

Small Case Lithium Battery

The AG-1201 battery 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 savings 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 AG-1601).
• Race and Track Day use 1500cc.
• Custom builds up to 1200cc. (If using a high-performance motor use the Antigravity AG-1601).
• 4 Cylinder Race Cars up to 1800cc.

Small Case Lithium Battery

The AG-1601 is an ultra compact 16-Cell battery: only 4.5″ Length x 3.25″ Depth and 5.25″ Height (to the top of the terminals) yet has massive power. It can turn over many of the larger V-Twin motors up to 113 cubic inches. This battery is often chosen for Custom V-Twins where small size is needed, and by Adventure bikers who want more power and capacity. AG-1601 is also a favorite for Race Car use.

Best Uses
