This 27+ hole (200A) Lithium Buggy Battery is designed especially for buggies that use twin motors. As it has the same footprint and is the same phisical size, it will fit within the battery bay on one side, where one of your original lead acid batteries fitted. Although designed to be used on twin motor buggies, it can also be used on buggies with single motors. Giving a greater range than 33Ah model.
