Battery Use and Maintenance

Battery Level Indicator

• When the Indicator Button is pressed, the Indicator will light up to show the percentage of the battery. The indicator has 5 sections. Each presents 20% of the battery level. When charging, the indicator will flash to show the charging progress. They will stop flashing when the battery is fully charged.
• If all 5 sections flash, it means the battery has fault. Please contact your dealer for consultation.

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.

Using Environment
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.

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.

Charging Environment
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.

ATTENTION: Do not charge the battery below 0°C.
WARNING: Using non-original battery chargers may lead to leakage, overheat, smoking, fire or explosion.

Charging Methods

Charging on the Scooter
Open the saddle, open the cover of the connector, and plug the charger into the charging socket.

Charging the Battery
Remove the battery from the scooter. Connect the charger with battery and socket.

WARNING
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.

ATTENTION
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

Before Riding
Please check the following details before riding.

Steering Handlebar

| (1)  Steadiness

(2)  Steering flexibility

(3)  No axial displacement or loosening

Braking| Braking lever has 5 to 9mm idle travel.

Tyres

| (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.

Battery| Adequate for planned distance to travel.
Lights| Check all the lights—High Beam, Low Beam, Brake Light, Turn Signal Indicator, etc.
Horn| Check whether the horn can work.

Braking Precautions
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.

Maintenance and Repair

Users are advised to have the scooter checked and maintained on a regular basis, even for the scooters that are not used for a long time.

Regular Maintenance
Users are advised to have their scooters checked 2 months after purchased or with 500 km travelled distance. Overall check and maintenance is advised to be conducted every 6 months or 3000km thereafter.

Daily Maintenance
If any problem occurs during checks, please look through the Home Repair Instructions or send the scooter to the dealer’s for checks and maintenance.

Scooter Washing
Please use neutral detergent and water to wash the scooter. Use soft cloth to wipe the scooter after washing to prevent scratching.

ATTENTION
If the scooter is frequently used in overload, high-speed, bumpy or up/downhill riding conditions, the maintenance cycle should be shortened.
For more guaranteed quality and longer service life, please use original parts, which are under normal warranty.

WARNING
If incapable of repair or adjustment on his/her own, the scooter owner is advised to send the scooter to the dealer’s for maintenance and adjustment for the sake of safety.
Always choose a smooth surface road for repair and adjustment . If it’s necessary to repair the scooter during a ride, please mind the traffic.

WARNING
Do not use pressure washer to wash the scooter, especially around the battery compartment. Do not flush the rear inner mudguard, where the charger, controller and other parts are installed behind. If the charging port on the scooter is wetted, please do not charge before the charger dries off. Contacting your dealer is recommended.

Storage Method

Short-term Storage

• Keep the scooter in flat, steady, well-ventilated and dry area.
• Charge the battery to 50% full before storage to maximize battery life.
• Avoid exposure under sunlight and rain to reduce damage or aging.
