Winter weather is cold, toy cars also need good maintenance (1) Good maintenance to keep the car body clean and tidy, to prevent the corrosion of the car body or rotating parts caused by the sun and rain. The water level should not be higher than the center line of the wheel shaft when it is used in the rainy season or through the pool, so as to prevent the motor from being damaged due to water inflow. The tire should be inflated enough to reduce the friction resistance between the tire and the road. Always care about brake performance to ensure driving safety. If the selected motor is a brushed motor, ride for half a year (About 3 OOOkm) The special maintenance center should be required to maintain the electric wheel and replace the lubricant. (2) Multi-power uses the multi-functional advantages of the toy car. The most ideal way to use it is to help the car, to help the car, to help the people, to link the manpower and power, to save labor and power. When starting, use the pedal to ride to a certain speed and then accelerate with electricity. When driving uphill, with heavy load or against the wind, human riding helps, which can avoid super-large current discharge of the battery, improve the mileage of one charge, prolong the battery life and protect the motor. Of course, without giving assistance, the controller has a current limiting effect, and the toy car will not be damaged. (3) Frequently charging to develop a good charging habit, charging after use, so that the battery often maintains a high-power state. Due to the characteristics of lead-acid batteries, frequent deep discharge is not allowed, especially if the storage time is too long after power loss, which will lead to crystallization of chemical substances inside the lead-acid batteries, vulcanization of battery plates and shortening of battery life, therefore, semi-electric storage is a magic weapon to improve the life of lead-acid batteries. A fully charged battery must be charged once a month. When charging, use a matching charger in a cool and ventilated place to avoid high temperature and humidity. Do not let water into the charger to prevent electric shock.
