Our EV lead acid series is designed with high quality grid alloy enables the grid with features of anti-corrosion, low gas emission and excellent deep cycle performance, as well as high density and special deep cycle lead paste prescription is adopted to ensure extra-long cyclic life. The cycle life may reach 600+ cycles @80% DOD High Capacity and High Energy Density: Rocket EV Series is designed with adequate active material and higher electrolyte density to increase the battery’s capacity with certain dimension and weight, so as to keep the battery with high energy density to be compatible with most of the electric vehicles.
