12V battery maintenance:
12V battery will consume electricity during long-term storage. It is recommended to
connect the main battery for long-term storage to prevent draining the 12V battery.
In the case of vehicle not being able to start due to the power shortage of the 12V battery,
try charging the vehicle with the on-board socket to charge the 12V battery. Or ask your
local dealer to service or change the battery if it does not charge.
In order to prevent possible leakage, overheat, smoking, fire or explosion, please follow these
instructions:
The battery should be used at the temperature of -10°C to 45°C.
Do not expose to water, beverages or corrosive liquids.
Keep away from heat source, open fire, inflammable and explosive gases and liquids.
Please keep metal parts away from the battery compartment.
In case of undesirable odor, overheat or deformation of the battery, please disuse the
battery immediately, keep away from the battery and contact your dealer.
Using Environment
WARNING: The MQi GT EVO battery is NOT a repairable part by the user. In case of
battery fault, please contact your dealer. Users dismantling the battery may lead to leakage,
overheat, smoking, fire or explosion. Do not attempt to open or repair the battery, as any
attempt to do so will render the warranty invalid.
The battery should be charged at the temperature of 0°C to 35°C. The charging time should not
exceed 24 hours. Overcharging will shorten the battery life.
Charging Environment
ATTENTION: Do not charge the battery below 0°C.
WARNING: Using non-original battery chargers may lead to leakage, overheat, smoking,
fire or explosion.

scooter. Connect the charger with
battery and socket.
Charging Pot

2625
All operation should be strictly conform to the user manual. If not, result will be
assumed by user.
Must use original charger.
Pay attention to the type of battery and applied voltage. Mixture use is forbidden.
Charging should be in ventilated environment. DO NOT charge in closed space or under
high temperature. DO NOT put charger into trunk or tail box while charging.
While charging, connect battery with charger before connect with electric supply. After
full charged, cut off the electric supply before cut off the battery plug.
When the green light turns on, please cut off the power in time. Avoid long time
connection between charger and AC power supply while not charging.
While charging, if the signal light is abnormal, has different smell or the charger is over
temperature, please stop charging immediately and check or change the charger in
time.
When using and storing the charger, please avoid foreign matter, especially water or
other liquid in case of internal short circuit.
DO NOT bring charger within scooter, if have to, please make sure of damping.
DO NOT disassemble or change the parts in charger by yourself.
WARNING
If the battery can not be fully charged after 12 hours, please stop charging and contact
your dealer.
To maximize the battery life, please keep the battery percentage within 20% to 80%.
For storage, please keep the battery under 40°C to prevent irreversible capacity loss of
the battery.
MQi GT EVO battery will lose more capacity in lower temperature conditions. To be more
pecific, the usable capacity at -10°C is 70%, 85% at 0°C and 100% at 25°C.
The best battery capacity performance for storage is 50%. Storing battery with less than
10% or more than 90% over a long period of time will cause irreversible capacity loss to
the battery.
The battery needs to take out from the scooter for storage longer than one week. In this
condition, please keep the battery at the temperature of 0°C to 20°C with capacity of
30%-70%. It's advised to have at least one cycle of charge and discharge every 2 months
to minimize battery capacity loss during storage.
If the battery failure is due to misuse or lack of proper maintenance as instructed, its
warranty will be invalidated.
Falling may cause uncontrollable internal damage to the battery and may cause
leakage, overheat, smoking, fire or explosion.

DOs and DON'Ts while Riding
Please check the following details before riding.
Before Riding
Check Point Description
Steering Handlebar
Braking
Tyres
Battery
Lights
Horn
Braking lever has 5 to 9mm idle travel.
Adequate for planned distance to travel.
Check whether the horn can work.
Check all the lights—High Beam, Low Beam, Brake Light,
Turn Signal Indicator, etc.
(1) The air pressure range of the front tyre is 25 to 34 psi
(2) Proper tyre tread depth
(3) No cracks or openings
(4) Minimum load-capacity index: front 25, rear 48.
(5) Minimum-speed category: J.
(1) Steadiness
(2) Steering flexibility
(3) No axial displacement or loosening
Adjust the scooter upright before applying brakes.
If the tyres are locked and the scooter loses steering ability resulting from excessive braking
force, loosen the grip on the braking lever and the tyres will be working again and the scooter
will be stabilized.
Try to maintain a 1:1 ratio of front and rear braking force on slippery roads.
ATTENTION: Inexperienced riders tend to use the rear brake only, which will accelerate
the wear of the brake and result in a longer braking distance.
WARNING: Using the front brake or rear brake only is dangerous because of possible
grip or control loss. Pay extra attention and use the brakes gently when riding on damp,
slippery roads and around corners. Otherwise, riders will be exposed to great danger.
Braking Precautions
