Product Description

This is the smallest battery in the Antigravity Batteries line up. At a miniscule 4.25″ Length x 1.25″ Depth and 3.75″ height (to the top of the terminals) this battery offers extreme power in the most compact size in Lithium Motorsport batteries. This battery is best used for applications where extreme weight loss and ultra compact size are desired. This battery is often chosen for Performance applications where compact size and low weight are desired. Can start inline 4-Cylinder motors up to 600cc for race use, or up to 250cc for everyday street use in scooters Also a favorite of custom builders who want the smallest battery to tuck out of the way.

Best uses

Capable of every day 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 Batteries AG801)
Race and Track Day use in inline 4 cylinder 600cc sport bikes- (Honda CBR600 rider should use the Antigravity Batteries AG801)
Custom builds like cafe racers or small bore customs up to 350cc. (Please note if you use older classic bikes from mid 1980s and earlier you should update the charging sytems to a modern voltage regulator, damaged voltage regulator can overcharge the battery and damage it)

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.

Amazing 4cell

The battery is so small and light compared to the old lead battery. There are so many places it can be fitted to the bike (brat project).

Very good quality product, super light 430grams and hassle free delivery. Also bought the mount for this battery - A little pricey but well worth it as looks great and holds the battery secure.

The battery is tiny and lightweight exactly as specified but it would have been nice not to have paid £10 for next day delivery (cheapest option!).

Really pleased with this awesome product. Could not believe the weight & size. Got this for my custom Honda FMX 650 where there was no space to mount the original battery. This small battery has no problem starting my bike. Would highly recommend!
