According to the investigation, the battery has become the biggest problem after the sale of electric bicycles, which seriously plagued consumers. The convenience of electric bicycles is inconvenient because of battery problems, so the convenience of electric bicycles is greatly reduced, so consumers are purchasing electric bicycles. Should you pay attention to the problems of the battery during the process? First focus on the battery's capacitance and voltage and other indicators. The battery is the most important power source for electric vehicles. The battery is a combination of voltage and capacity. Different combinations, capacity, power, and driving distance are two to three times different in price. Therefore, when purchasing, it is necessary to find out how many volts and how many amps the electric vehicle battery is. Under normal circumstances, the electric vehicle battery 48 volts 20 amps is longer than the 36 volts 10 amps after full charge. Generally speaking, the battery capacity and power are higher, and the price is correspondingly higher. Secondly, you should ask about the warranty period of the electric vehicle and the specific warranty content. Merchants generally promise that the battery warranty is one year, but the business said that the "one year" is divided into time slots: generally refers to the quality problem within six months from the date of purchase, replace the new battery, six months to a year to replace The old maintenance battery is not responsible for any problems that occur after one year of use. Therefore, when purchasing a battery car, consumers should negotiate with the merchant for the specific warranty period and corresponding contents of the battery, and indicate on the warranty card to avoid consumer disputes. Finally, choose the brand, service and word of mouth. Brands, services and word of mouth are the best ways to promote electric cars. When consumers buy, they must not only choose a good quality battery car, but also a service than the brand, pay attention to understand whether the product has a service point in the region, how to reputation in terms of service quality and reputation, so that the electric vehicle will fail in the future. It can be solved in the shortest time. Whether it is a battery or an electric bicycle, you should pay attention to the purchase, follow the principle of carefulness, and the company should pay attention to quality, pay attention to after-sales service, so that electric bicycles can truly bless the consumers! bmw angel eyes,bmw light,bmw laser lights,bmw led headlights,bmw f12 headlight,bmw g05 laser lights PNP Car Light & MAYLERESCAPE LIMITED , https://www.pnpcarheadlights.com
