Leasun Lithium Battery Class
Leasun Smart Lithium Battery works with users to better and safer use of lithium batteries through the correct use of lithium batteries. Let's enjoy our ride together!
◆ The charger specially configured or recognized by the company must be used for charging, otherwise the battery life may be shortened or the battery may become invalid;
◆ When charging, it is forbidden to directly contact the positive and negative terminals with conductive objects;
◆ It is recommended to charge the battery at 0 ℃ - 40 ℃ for daily use;
◆ When the battery leaves the factory, the battery power is about 50%, and the new product needs to fully charge the battery before use;
◆ It is not allowed to charge the lithium battery at home according to national regulations. When charging, please place the charger and battery in an open and safe place that is stable, dry, free of flammable and explosive substances and out of the reach of children;
◆ During charging, the charger may generate heat, which is normal as long as the battery temperature does not exceed 60 ℃;
◆ The battery must be charged within 24 hours after full discharge, and the charging time shall not be less than 3 hours;
◆ This product can only be used on electric bicycles with matching electric performance as specified, and cannot be used on other electric equipment, otherwise it will not be guaranteed;
◆ The controller, motor, horn, lighting equipment, etc. of the electric vehicle are damaged or improperly configured, which will cause the battery to discharge with high current. At this time, the battery will also stop outputting protectively, and it can be recovered after the power is turned off and restarted, without any impact on your riding;
◆ Applicable ambient temperature range of this product: - 20 ℃ to 45 ℃; Like all other batteries, the available energy of the battery will decrease with the decrease of temperature, which is a normal phenomenon;
◆ When using the lithium battery, avoid water ingress into the battery, beverages and corrosive liquids, which may cause the battery to leak, heat, smoke, fire and explosion;
◆ It is forbidden to use more than two groups of batteries in series and parallel without permission, otherwise the warranty will not be provided;
◆ If the lithium battery needs to be stored for a long time (more than one month), it is recommended to charge it to 40% to 60%. During the storage period, the battery should be recharged for 1-2 hours every month. The lithium battery should be stored in a cool, dry and safe environment;
◆ Avoid metal objects entering the battery box during the storage of lithium battery, which may cause leakage, heat, smoke and fire of the battery;
◆ Avoid putting the lithium battery near the heat source, open fire, flammable and explosive gas and liquid, which may cause the battery to leak, heat, smoke and fire;
◆ It is forbidden to disassemble the battery or modify the battery without permission, otherwise it will not be warranted;
◆ This product should be repaired by our professional maintenance personnel or the maintenance department designated by our company. If you open the battery case by yourself, the warranty service will be terminated;
◆ Our company will not be responsible for any problems caused by opening the battery shell or refitting the battery;
◆ If the battery is deformed or hot, stop using it;
◆ If the battery catches fire, it is recommended to use a large amount of water or dry ice extinguisher (carbon dioxide extinguisher) and thick cloth soaked with water to cover the fire;
◆ The company will not be responsible for battery failure caused by not charging the fully discharged battery in time;
◆ Do not discard this product at will;
◆ The battery cannot be charged: first check whether the charger is invalid, replace the charger for charging, and contact the purchasing store and our customer service as soon as possible for other reasons such as battery fuse, protection board, battery internal failure, etc.
◆ The battery cannot be discharged: please test the battery with another matching vehicle to eliminate the cause of the original vehicle failure. If the battery cannot be discharged, confirm that the battery failure may be caused by the failure of the battery fuse, protective plate, battery pack, etc. Please contact the purchasing store and our customer service as soon as possible.
◆ The battery can not run far: 1. After long-term use or long-term non use, the capacity of the battery will naturally decline. The longer the battery is used, the smaller the capacity will be; 2. The battery's range is shortened due to temperature, especially when the temperature is 45 ℃ or below zero, the battery capacity will decline to a certain extent, which is a normal phenomenon; 3. Affected by vehicles, electric vehicles have been used for a long time, and the internal electronic control accessories, including motors, controllers, lights, connectors, lines, etc., are aging. The efficiency decreases, the internal resistance increases, and the battery load increases, which will also affect the battery capacity and reduce the driving range. In addition, the tires are checked frequently. Insufficient tire gas will also increase the driving resistance and affect the driving range; 4. The battery's range is affected by the actual road conditions. Frequent starting and stopping, climbing, excessive wind resistance, etc. will increase the battery's power consumption, resulting in reduced battery range. To sum up, when consumers feel that the endurance mileage is seriously insufficient, they should first check whether the battery is fully charged. If the battery has not been used for a long time, please contact the purchasing store and our customer service as soon as possible to conduct a professional test on the battery.
◆ Cycling power failure: the main reasons are the vehicle control protection and the protection of the protective plate inside the battery. The causes are that the battery does not match the vehicle, the controller output current is too high, the battery protective plate is powered off for protection, and the second is that the battery fails, the controller protection or the battery protective plate protects itself. This situation requires our professional testing. If the power failure occurs, please disconnect the battery and the car's discharge wire and reconnect them, Restart the vehicle. If the vehicle cannot be started or the power is cut off frequently during cycling, please contact the purchasing store and our customer service as soon as possible.
