Chevalier series improves motor torque and MPG by momental charge and discharge. We evolved "Chevalier boost" corresponding to the transformation more in high current. It cope with a surge to be generated at the time of an electric current and a run at a moment at the time of the use of Boost/Turbo. It balance Large-capacity and low resistance, reduce time lag at a moment at the time of the throttle operation and show an extremely high effect in all speed area. In addition, it is effective for heat generation of ESC, motor and battery.
