2. Operation
2.1 Battery
2.1.1 Start usage
To install the battery, please put the battery inside the cradle and push it until
locked.
To remove the battery, please turn the key and pull the battery out from the
cradle at the same time.
LED behaviors :
(1) Charging : One way scrolling (from 0 to current level)
(2) Fully charged : LEDs all ON
(3) Power on progress :
LED 1 –ON : 6% ~ 20%, FLASH : 0% ~ 5%
LED 2 –ON : 21% ~ 40%
LED 3 –ON : 41% ~ 60%
LED 4 –ON : 61% ~ 80%
LED 5 –ON : 81% ~ 100%
(4) Power off progress : LED 1, 3, 5 are ON

2.1.2 Charge
1. General use instructions
A. Connect the cable from charger to battery, and then insert the plug.
B. While the charger starts charging, the led shows red color.
While the charger standby or finishes charging, the led shows green color. If you
are done charging, disconnect the charger from the battery before removing the
power plug from power socket.
2. Charging time
The charging time depends on the remaining energy in the
battery and the charger current. The acceptable charger input
voltage is AC 100 - 240 V ~ 4A (50 / 60Hz).
If the battery is completely discharged, you can estimate the
charging time by the following calculation example：
The estimated charging time is the battery’s capacity divided
by the charger’s current. The standard new X1 max battery is
11 Ah and the standard new X1 max charger is 4A.
Estimated charging time = 11 / 4 = 2.75 hours

2.1.3 Important safety notes for battery charging
Use only the battery charger delivered with the product.
Use only dry charger, undamaged power cable and charger.
Replace damaged power cable and charger immediately.
Remove any possible foreign object from the charging socket, such as dusts, ice
or snow before plugging in.
Using any battery charger other than the one delivered with the product may
cause overheating of the battery or even a risk of explosion.
Deep discharging of battery may result in internal damage.
There is a fire risk if the temperature of battery rises up to a dangerous level.
Avoid deep discharging of battery while in use or storage.
If not in use, the battery should be charged fully at least every 3 months.
Do not expose the bike in a storage temperature lower than -20°C (-4°F) or
higher than 60°C (140°F). Please note that the internal structure of battery may
be overheated to damage due to high temperature greater than 60°C,
particularly exposed to direct sunlight.
Do not use the charger at a humid place or an ambient temperature lower than
-10°C (14°F) or higher than 40°C (104°F).
The battery and charger are maintenance-free. Do not attempt to disassemble or
modify the battery or charger.
Do not expose the battery to high voltage.
It is advised not use battery with damaged casing.
Do not cover the battery or the charger while charging is in progress.

2.2 HMI
2.2.1 Display information
Speed
Display of current speed, and precision is decimal point one.
Assistant level
There are totally 3 levels for choice when you are riding.
When the system is turned on again, it will return to "0".
With level 0 you will feel like riding a regular bike without any electrical assistance.
With level 3, it will support you the maximum power.
Battery capacity
The battery sign on HMI will tell you how much capacity is left in your battery when
the system is on. The following illustration shows how much power is left.
96% ~ 100% 81% ~ 95% 61% ~ 80% 41% ~ 60%
Flash
21% ~ 40% 1% ~ 20%0%
Battery capacity is 0% when the battery light flashes, please charge immediately.
