1. The official charger should be used only. The charger port should be well connected to
the battery connector. The non-standard or unqualified charger may cause a battery
fault and reduce battery life.
2. During charging, the charger should be placed in a ventilated environment; it’s strictly
prohibited to charge under a burning sun, in a closed space or high-temperature
environment.
3. The charging time should be at least 3 hours. In order to have 100% charged, please
continue charging for 1~2 hours after the charger indicator turns to green. The battery
must be charged within 24 hours after it’s entirely run out. The battery needs to be
charged for 3 to 10 hours before use.
4. Please do not drain the battery entirely during riding. Please charge the battery as soon
as possible when the last bar of the display’s battery indicator is on. It will affect battery
life if the battery entirely runs out.
5. It is forbidden to place the battery for a long time if the battery already runs out. If the
battery still has not been charged for more than a month, the battery capacity will be
reduced by 5%. It is recommended to charge the battery before use. If the e-bike won’t
be used for a long time, it’s recommended to charge the battery once a month to
prolong the battery life and prevent the battery from losing electricity.
6. Put the charger and battery in a stable, dry, inflammable, and explosive-free place.
Keep them away from children. During charging, the temperature of the charger might
go high; it’s normal as long as the temperature does not exceed 55°C/140°F.
7. Prevent metal from short-circuiting the charging port.
8. After the battery is fully charged, unplug the charger from the socket first, then
disconnect the charging port from the battery.
9. Waste batteries can’t be discarded randomly or disassembled arbitrarily.
