    I bought a 24 cell 720 CCA unit. It started my 127 cubic inch motor first time. Delivery of battery the fasted I ever had of any product I bought from the US to Macau / Hong Kong – 5 days.
    Although the 24 cell battery is quite expensive, but I still feel worth the money.
    I will recommend your product to my friends who ride big bikes.
    On a other note: I work in the aviation industry, the company should consider developing products based on your battery technology to serve the aviation sector.

    My PC925 Odyssey died a few weeks back. I liked the PC925 (26lbs) and has never let me down, but I was tempted to try the PC680 (15.4lbs) to save some weight. I went shopping at my local battery store, and the sales person mentioned that the PC680 was used on some motorcycles and that there were some Lithium motorcycle batteries that were substantially lighter….

    As a result I left the store without buying a replacement battery and started researching about Lithium batteries. I Emailed the Antigravity folks several times to ask technical questions and all were answered promptly.
    After doing all my researched I decide to buy the Antigravity YTX12-24 Battery “;” with 720 Cranking Amps at 5Lbs… (That is 21lbs less that my current the PC925 and 10.4lbs less than the PC680 (but with more Cranking Amps). That is more than sufficient to start a 3.4L 348 Ferrari.

    I had to fabricate a battery tray for the Antigravity battery. Once all was installed and connected, the car fired up great!

    After a few days of driving with the new battery I have a few positive observations. First, the battery voltage seems to be steady and the car starts very well every time ( just like if I had a fully charged lead-acid battery). With the reduced mass the car feels lighter and seems to accelerate better. However, this is a very subjective seat-of-your-pants indicator.
    One observation, that is very apparent, is that the car does not seem to overseer as much. When I took the car on a few twisty roads, including a tight roundabout , the back end was definitely more stable and planted to the road. So far, this is a great performance modification and look forward to my next track days. The only drawback, due to smaller reserve capacity, is that I have to keep a close look at battery drain when the car is not used for a few days. However, this is a minimal inconvenience for improving the cars performance…..

    We’ve tried 4 brands of Li-ion powersports batteries and Anti-Gravity is clearly the best in starting power, reliability, packaging and customer service. Thanks guys!

    I had a brand new Odyssey battery with 310 cranking amps and it would barely engage the starter, on my custom chopper with a large SS v-twin.

    This 720 cranking amp battery spun it over in 33 degree temps in my garage and fired it right up.

    I purchased this battery for a custom build I was working on for a year and needed a small form battery that would start my high torque starter and high compression motor. I tried a Ballistic battery first and all it would do is push the jackshaft to the pinion and get stuck. I promptly returned that battery and called Antigravity. They set me up with the YTX-24 cell and gave me a good discount. Bike now starts on the first push, no delay in 30 degree temps. I could not be happier with the product performance and the craftmanship of the battery.
