A good bumper car, in addition to its own good internal quality, is also closely related to normal maintenance and correct operation and use. Developing good use habits and reasonable use methods play a vital role in the service life of batteries and motors. Do good maintenance, more assistance, and frequent charging. (1)Good maintenance Keep the car body clean and tidy to prevent 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-help Taking advantage of the multi-functional advantages of bumper cars, the most ideal way to use them is to help people with cars, to help people with electricity, to link manpower with electricity, to save labor and electricity. 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 bumper car will not be damaged. (3) Frequently charging, develop a good charging habit, charge 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.
