1. Check the circuit frequently to see if there is any corrosion or fracture. If there is aging, wear or poor contact of the circuit, it must be replaced in time. Do not continue to use it, so as to avoid contact point fire and series electric accident. 2. When charging the battery, you must choose a wide space. Do not charge the battery in a closed space, to prevent explosive mixed gas from generating and causing the battery to explode. 3. The charging time is within a reasonable range. Be careful to charge for a long time at night. The normal charging time is eight to ten hours. If it exceeds ten hours, it may lead to overcharge and damage to the battery. If it is less than eight hours, it may lead to insufficient charging, affect the capacitance, and reduce the endurance and service life. 4. Be careful when climbing or starting. When climbing, it is recommended to use pedals to help you to prevent the motor coil from being damaged because the starting current is too large and the machine parts are overloaded for a long time. Whether using electric motorcycle, electric bicycle or electric moped, reasonable use can prolong the service life of the car and ensure your travel safety.
