Surfboard Jet Scooter Surf Float Fzblue Origin Type Gua Place Model Sea Engine Electric

Optimized compared to the first generation: the brake failure of speed governing handle, and the speed governing trigger conflicts with the safety switch (which cause failure of safety switch and cannot close the surfboard). The carbon fiber shell is a unicase. The shell is embedded and integrated with the carbon fiber shell and the nuts are fully covered to avoid the risk of water inflow. The battery capacity is 48Ah and the first generation is 27Ah. It is fully encapsulated to avoid the failures caused by water or moisture. 
                    The motor power reaches up to 10kw while the first generation is 7.5kw. The controller is increased by 50% for sink margin compared to the first generation, and has lower failure rate. The propeller, made of carbon-plastic composite material, is light in weight and corrosion-resistant, which can avoid the oxidation problems of aluminum alloy or stainless steel. The optimized structure is more convenient for replacement, while the first generation cannot be replaced. For the power system, this generation applies the sealing liquid cooling for the cooling mode with temperature sensor. The first generation applies the open water cooling type, and foreign matters may rush into the motor from the cooling port with water and cause blockage or rustiness of the motor. The new generation of products will not have the above problems.                                                                                                 The battery protection board of the first generation has only one switch to control the charging and discharging. There is also output at the charging port during discharging, and water may inflow during use and cause short circuit of the charging port. The battery protection board now is in separate control of charging and discharging. The charging port only has electric input during charging and there is no electric output under any circumstances.
