Problems solved by technology

A strong and stable battery pack generally includes a box and the battery pack inside it. When using it, it is necessary to ensure that the ambient temperature around the battery pack is between 20 and 25 degrees, otherwise it will affect the normal charging and discharging of the battery, and the ambient temperature The primary method of control is to cool down, because the battery will definitely generate heat during the charging and discharging process, resulting in a sharp increase in the temperature of the surrounding environment
