Antigravity ATX30 Hi Performance Lithium Motorcycle and Powersport Battery, Most Power in Class, Group 30, UTV, Tractor, Generator, Harley, Victory, Indian,

As my battery location is in a location very deep within a Tri Glide Ultra Motorcycle installing was very easy due to its extreme light weight. Harley Davidson employs a battery cover that makes it difficult to use the restart button, so a small modification to create an access hole to make it easier. I can’t wait till the remote start becomes available. The restart employs a second backup battery for a few starts if the main battery is asleep or drained. Read the instructions, it will be worth it.

this thing is great, definitely pricey but if you are looking to drop 25-30 pounds off your car this will do it. installed on a 2001 Trans Am WS6 and I was skeptical whether it would crank it or not but it turns over a stock ls1 as fast as any "normal" battery Ive ever had. Would recommend if you can stomach it being roughly double the price of a quality lead acid unit. Assuming it lasts I will definitely buy another.

After riding about 50 miles with this battery my 19 Road Glide began having a bunch of electrical problems. Voltage gauge would climb to 16v and drop to 12v. Radio would cut out and all other gauges would shut off. System test revealed voltage codes, BCM codes, ECM codes, and radio codes. Installed factory battery and all faults went away. Reinstalled the Antigravity battery and all the faults reappeared within a few miles of riding.

Amazon says this is compatible. After much troubleshooting I found out the battery is NOT compatible with my bike

this battery cranks my 427 c.i 12.1 compression ls3 motor with ease repeatedly. Very good value

Installation in 2021 HD Ultra limited. Very expensive battery and no hardware. This product is supposed to have hardware supplied from the factory, but didn't know until after installation with my own hardware. Hopefully will get good results for years to come.Don't forget registration for warranty with Antigravity.com

Installed in autocross/track car (Nissan 350Z) 4 months ago. So far so good. The vehicle sits for 1-3 weeks between events, sometimes in sub-freezing temperatures. Starts every time.

Haven't used it to start my small block hot rod yet but the small compact light weight sure fits the bill.Stay tuned
