There are two ways to charge your battery.
1. Charge the battery ON the bike
1) Find the Charge Port at the bottom of the downtube.
2) Pull out the cover to show the charge port and insert the charger output plug into the
port. Connect the input plug to the power supply.
2. Charge the battery OFF the bike
1) Take off the battery from your bike.
2) Place the battery in a clean and flat place in room temperature.
3) Insert the charger output plug into the charge port. Connect the input plug to the power supply.
4) There is a capacity indicator at the top of the battery. Press the button beside to check the charge
status. Green means sufficient of charge. Yellow means less than 90%. Red means less than 10%.
Notes of Charging:
1) Charging time varies from 8 to 10 hours. Never charge a battery for more than 12 hours at a time.
2) The small LED light on the charger in RED indicates it is in charge; The small LED light on the
charger in GREEN indicates it is fully charged.
3) Insufficient charging will not influence the battery lifecycle. AVOIDING deep discharge is helpful to
protect the battery and extend its lifecycle.
4) If the battery will not be used for a long period, take it off from the bike and discharge its capacity to
60%-80% for stock. Disconnect it from the charger and place it in a dry, ventilated place without
direct sunlight. In order to maintain a long lifecycle, it is recommended to charge the battery
every two months even when it is in static without use.
5) Pay attention to check whether the surface temperature of the battery case rises too high during
charging. It is FORBIDDEN to cover the battery during charging.
6) Due to high temperature in summer time, it is NOT advisable to charge it immediately after riding. In
winter, it is FORBIDDEN to charge the battery in environment below 0℃. You are recommended to
charge it in room temperature.
