The Lightest, Most Compact, Most Powerful Battery For Your V-Twin

A light weight battery with massive power able to start over and over bikes up to 135′ motors and that you can easily hide is the dream of all custom builders. A company called Antigravity Batteries makes such a claim for street motorcycles up to 1800 cc, all this in a very light package of 3.1 pounds package measuring only 4.25″ Long  x 3.0″ Wide x 5.0″ Tall.

This company designs and builds in the USA a full line of motorsports batteries using the best Power Cells and material available manufactured by the American based company who provides lithium batteries for Ford, GM, Toyota, Tesla just to name a few.

Antigravity Batteries claim that their batteries are: 1- The most powerful in the smallest, lightest package that is available today with sizes from 1/2 to 2/3rd smaller than a typical lead acid battery, yet putting out twice the cranking amps. 2- A dramatically better starting with a larger ignition spark due to the fact that the voltage stays much higher on the starting pulse than lead/acid batteries. 3- A much ligther weight, on average 75-80% lighter than the lead acid battery they replace.

These batteries are used by Professional Road Racers, Motocross, Car Race teams as well as CustomB builders, many of whom were competing this year in the Sturgis bike shows. Check out the complete line up of available batteries at Antigravity Batteries.

    Don’t these use Taiwan made A123 cells?

    Since the cells come in various round cylinders sizes it would be easy to stringing them in a line and slide them into the frame rails for a really clean no battery at all look.

    These lithium Iron batteries are the way to go. Shorai also have some great batteries and the posts are not straight up.

    135 cu in and 1800cc are not even close. more like 2212cc.
    so what are they rated for and how much they cost?

    They show pricing on their website. You’ll be looking at $200-$300 depending on the application. Their 12-cell has 450 cranking amps, is recommended for street bikes up to 1300cc, weighs 2.4 lbs., and retails for $219.00. They have several cell-count options.

    One day not long ago these prices would seem INSANE. But has anybody priced out a AGM battery via HD for say a bagger? You’d think highway robbery would be more pleasant. It’s a nice option to have such products. Too often us HD riders really never consider weight, and we should.

    I love that My Road Glide will perform the same with this new battery weighing in at 10 Lb. less. It leave me room to eat 2 Fine Meals at the Palm!

    I have used Voltfreaks and Braille with similarly disappointing results. Some , but not all of these type batteries cannot be recharged if their voltage is less than 9 or so –a battery tender is manditory.
