2. Choose capacity
The capacity of the battery is determined according to the cruising range and the size of the motor, which can be roughly calculated according to this formula: Lithium battery voltage, lithium battery capacity, motor wattage, electric vehicle average speed = cruising range
3. Choose a big brand
With the popularity of the lithium battery industry, many small companies or workshop-style factories speculate in this industry, which also causes the quality of lithium battery products to vary, making it difficult to distinguish between true and false. The easiest way is to choose a big brand, which is more guaranteed in quality.
4. Check whether it meets the national standard
The national standard is the standard for quality assurance. It depends on whether it conforms to GB36972-2018 "National Standard for Lithium-ion Batteries for Electric Bicycles". If the product does not have this standard, it can basically be ignored.
5. Look at the qualification of the manufacturer
Look at the scale of capital, like lithium battery production and research and development, need to invest a lot of money to complete, the registered capital is less than 100 million, basically are workshop-style factories, and whether there is an official website If a company does not even have its own official website, it does not need it Considered.
3. Electric vehicle lithium battery price
