The Antigravity YTX20 is a Lithium battery to replace the OEM Lead/Acid Battery often called the YTX20, YTX20L, YTX20H, YTX20-BS or the "20 Size". The OEM standardized size of the YTX-20 is used in a many different manufacturers models of Motorcycles including Harley Davidsons, Victory, Metric Cruisers/Tourers as well as many Powersport Vehicles such as UTVs/ATVs, Snowmobiles and more. In comparison, Antigravity's Lithium-Ion version offers impressive weight savings at only 4.68 lbs, and OVER 2.5 times the Cranking Power of the Lead/Acid version! So those difficult-starting large Custom V-Twin Motors can be turned over with ease. The Antigravity YTX-20 battery can also be used in Hi-Performance Automotive and Racing applications where extremely high cranking power and massive weight reduction in a very compact size are desired. As with all our batteries, you can easily bolt on our Automotive Terminal Adapters for use in high performance automotive application. The negative terminal is on the left side.
