1. Place the power supply

　　 Lithium-ion battery packs have some remaining power before they leave the factory, and they can also be used for short-distance riding after electric vehicles are sold. After the first ride, the battery must be charged for the first time. It is recommended that the first charge should be carried out for a long time. The lithium-ion battery pack should be charged in time after use. Do not store it at a loss. If the battery has not been used for more than two months , The lithium-ion battery pack needs to be fully charged once.

　　2. Notes on charger

　　In order to ensure the safety of charging the lithium-ion battery pack of electric vehicles and ensure the service life of the battery pack, the battery pack uses the supporting lithium-ion battery charger. If the charger is lost or damaged, please buy it from the corresponding dealer. Do not use lead-acid chargers or other forms of chargers for charging.

　　3. Do not change the charger casually, and do not remove the speed limit of the controller

　　The chargers of various manufacturers generally have individual requirements. Don't change the charger at will when you are not sure. If the continuation mileage requirements are relatively long, it is necessary to equip multiple chargers for charging in different places. The chargers for supplementary charging in the daytime should be supplemented with chargers, and the original chargers should be used at night. Removing the speed limit of the controller can increase the speed of some cars, but in addition to reducing the safety of the car, it will also reduce the service life of the battery.

　　 4. Charge in time

　　 The vulcanization process began after the battery was discharged, and obvious vulcanization appeared after 12 hours. Charging in time can remove non-serious vulcanization. If not charging in time, these vulcanized crystals will accumulate and gradually form coarse crystals. Therefore, in addition to daily charging, you must also pay attention to charging as soon as possible after use, and use lithium as much as possible. The ion battery pack is fully charged.

　　 5. Pay attention to the charging environment

　　The best ambient temperature for charging is 25℃. At present, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging at 25°C is better.
