Factors you must consider when choosing a battery

　　Factors that must be considered when choosing a battery:

　　1. Usage performance: Lead-acid batteries are generally within 400 times, and the service life is about 2 years. Lithium batteries are durable, consume slowly, can be charged more than 500 times, have no memory, and have a service life of about 4-5 years.

　　2. Capacity: Generally, lead-acid batteries have a net weight of 16-30kg and are very large in size; lithium batteries are generally -3kg in size, are smaller in size, are light to ride and easy to transport.

　　3. The popular rechargeable battery on the market is 48V. If you replace the lead-acid battery, the price is about 450 yuan, and the warranty period is about one year; the lithium battery is relatively expensive, costing about 1,000 yuan, but the warranty period is 2 Year.

　　4. Driving process: With the same 48v rechargeable battery, when the battery is charged, lead-acid battery and lithium battery electric vehicles can drive 30-40 kilometers. The key to drive speed is the size of the common motor.

　　5. Battery capacity: lead-acid battery capacity is about 20 amps; lithium battery capacity is 8-10 amps.

　　How to choose the battery voltage? There are various types of electric vehicles on the market, with voltages of 36v, 48v, 64v, 74v, 80v, etc. How should customers choose it? The higher the working voltage, the better the characteristics and rationality of pure electric vehicles. . The overall performance of electric vehicles equipped with five or six batteries is better than that of electric vehicles equipped with four batteries. The long-term use of pure electric vehicles is also more convenient than pure electric vehicles with 48v rechargeable batteries. However, due to the difficulty of manufacturing high-voltage pure electric vehicles, the vast majority of the market is still selling pure electric vehicles with four batteries, which is a more popular configuration.

　　At present, the price of pure electric vehicles with five or six batteries is slightly higher. The reason is very simple. In addition to technical factors, high-voltage pure electric vehicles also have a large number of voltage-adjusting power circuits, control panels, motors, window frames and other 48V powerful components. It is durable, not only powerful, fast, long-distance running, and has a long battery cycle. When consumers purchase electric bicycles with 48V or above, it is not recommended to buy small-power pure electric vehicles, such as 36V pure electric vehicles.

　　Purchasing Suggestion: Although lead-acid batteries are still the main product on the market, and lithium batteries are not widely used due to their high prices, the editor recommends that consumers purchase lithium-ion electric vehicles that are lightweight and easy to disassemble. Not only do they have better performance Strong, easy disassembly and assembly are also helpful to avoid theft of pure electric vehicles. Regarding the choice of battery voltage, 48V electric bicycles are better than 36V ones, and their overall performance is better, making them more suitable for ordinary consumers.
