OEM Size Lithium Battery (Direct Replacement)
Antigravity’s YTZ7-4 is a direct replacement in size for the standard YTZ7S. This 4-Cell version is best for use in every day use scooter and bikes up to 250cc; or Race bikes up to 450cc. With this battery you save about 3.5 pounds while offering similar starting performance. If your application is above 250cc we suggest the Antigravity Batteries YTZ7-8 which is the same size yet offers TWICE the power and capacity and will have a dramatic increase in motor turnover and starting while saving about 3 pounds.
