Read the instructions - lithium battery
The instructions are very important instructions for use, and there are ways to maintain them. You must read them one word at a time and look carefully.
Always remind us that many people who get electric cars will leave the instructions on the side, and they will choose the boring words. The general sequelae are that the motor is burnt out, the battery is blown up, and once the problem occurs, choose to customer service. Calling, in case the customer service can't solve it, it will waste a lot of time and money. And the general instructions will have a complete guide, as well as the correct test method and after-sales maintenance method of the battery. In fact, as long as you read the manual in detail at the beginning, you can solve the problem.
