Use a screwdriver to open the back cover and unscrew the three screws. You will see the remote control split into two halves—one with the circuit board and the other with the casing. Take the half with the circuit board and pry it open. You will find a gray component in the upper right corner. Lift it to reveal the encryption chip. Behind the button rubber, there are screws. Open it to see the battery inside. Remove the old battery and replace it with a new one.

How many kilometers can a 60V20A battery run?

This depends on the load, whether it's a new vehicle, and whether the motor is aging. If all the indicators of the electric vehicle are in optimal condition, a 70 kg person driving at a constant speed of 20-30 km/h without braking and on completely flat roads can run for 70-80 km. Tire pressure and load: Rear tire pressure—insufficient pressure will increase friction resistance and affect the range. Speed: If the speed is too fast, exceeding 30 km/h, there will be significant wind resistance, consuming kinetic energy. Vehicle performance: Whether the bearings are worn, the effectiveness of lubrication, and whether the brakes are locked up will all affect the range.

What are the signs before a scooter belt breaks?

Scooter belt breakage is preceded by an increase in engine noise. Scooter belts: Scooter belts come in two types: special core structure and cord core structure, each composed of four parts: wrapping cloth, top rubber, tensile body, and bottom rubber. The cord core structure V-belts are easy to manufacture, have average tensile strength, and are widely used. The special core structure V-belts offer good toughness and high strength, making them suitable for high-speed applications. Precautions: The transmission box of a scooter motorcycle requires regular maintenance, mainly to clean the dust inside the belt box and check if it is functioning properly. If the belt box is cleaned every 10,000 kilometers, belt breakage rarely occurs because the belt box is less likely to fail after cleaning and maintenance.

What is the difference between AT and ATT tires?

ATT is an off-road tire and the world's first crossover CUV all-terrain tire product. The difference between Cooper AT tires and ATT is that ATT has a larger contact area, providing better grip and shorter braking distance compared to AT, which also means Cooper ATT offers superior stability during driving and cornering. Below is additional information about ATT tires: Cooper ATT adopts wide and deep tread grooves along with a hinge-type tread design, clearly showcasing its off-road capabilities. It features a robust tire structure with strong impact and puncture resistance, effectively enhancing the tire's rigidity and stability at high speeds. Compared to regular SUV tires, it has a larger contact area, comprehensively improving grip and reducing braking distance, thereby enhancing vehicle stability during driving and cornering.

Where is the fuel pump installed?

The fuel pump is installed inside the fuel tank. Its function is to draw gasoline from the fuel tank and deliver it through pipelines and the fuel filter to the float chamber of the carburetor. Thanks to the fuel pump, the fuel tank can be placed at the rear of the vehicle, away from the engine and at a lower position. Fuel pumps can be divided into two types based on their driving methods: mechanically driven diaphragm type and electrically driven type. The diaphragm fuel pump is representative of mechanical fuel pumps, used in carburetor engines and driven by an eccentric wheel on the camshaft. The electric fuel pump, on the other hand, is not driven by the camshaft but relies on electromagnetic force to repeatedly move the pump diaphragm. This type of electric pump allows for flexible installation positions and helps prevent vapor lock.
