  • charging
  • storage
  • transport
  • rain or water exposure
  • a crash or impact
  • modification
  • third-party repair

If there is visible damage, please also prepare clear photos.

Safety Warnings

• Do not continue riding if the scooter has overheating, motor resistance, visible wiring damage, smoke, burning smell, or water exposure.
• Do not work on wiring while the scooter is powered on or connected to the charger.
• Do not force connectors together.
• Do not open sealed battery components.
• Stop and contact support if you are unsure about any step.

Scooter Will Not Charge

This issue may be caused by:

• Incorrect display voltage settings
• Charger faults
• Charging port faults
• Wiring damage
• Battery protection mode
• Battery faults

Step 1 – Check the Display Voltage Setting

The Kaabo Mantis King GT should have the display voltage setting set to 60V. 

If the display voltage is set incorrectly

Correct the setting and test charging again.

If the display voltage is already set to 60V

Continue to the charger checks below.

If the issue is resolved

The issue was likely caused by an incorrect display voltage setting.

If the issue remains

Continue to Step 2.

Step 2 – Check the Charger Indicator Light

Connect the charger to a power outlet and check whether the charger indicator light turns on. 

If the charger light does not turn on

The charger may be faulty.

Please contact support and provide:

• A photo/video of the charger
• A video showing the charger connected to power

If the charger light turns on

Continue to Step 3.

Step 3 – Check Charger Output

Connect the charger to the scooter and power it on.

If the charger light stays green, the charger output should be checked using a multimeter. For KAABO chargers, voltage should be measured between hole 1 and hole 2. 

If there is no voltage output

The charger may be faulty.

Please contact support with:

• A video showing the multimeter reading
• Photos of the charger model label

If voltage output is present

The charger is likely operating normally.

Continue to Step 4.

If you are not comfortable using a multimeter

Stop troubleshooting and contact support.

Step 4 – Check the Charging Port Connection

This step requires access to the battery compartment.

Only continue if you are comfortable performing this inspection safely.

Inspect the XT30 yellow terminal connection between the charging port and the battery for:

• Loose connections
• Damage
• Signs of melting
• Detached wiring 

If damage or a loose connection is found

Do not continue charging.

Contact support with:

• Clear photos of the XT30 connector
• Photos of any visible damage

If the XT30 connector appears normal

Continue to Step 5.

Step 5 – Inspect Charging Port Wiring

Disconnect the charger from power before continuing. 

Inspect the red and black wires connected to the charging port for:

• Detached wiring
• Exposed copper
• Broken insulation
• Shorting or melted wiring 

If wiring damage is found

Do not continue charging.

Contact support with:

• Clear photos of the wiring
• Photos of the charging port area

If no visible wiring damage is found

Continue to the battery checks below.

Battery Charging Issue

This section applies if:

• The scooter still will not charge
• The charger appears normal
• The charging port appears normal

Step 1 – Check the Charging Fuse

Disconnect the charger from power before continuing. 

Check the fuse on the battery charging port wiring.

The system uses a 5A fuse. 

A multimeter continuity test may be required.

If the fuse fails the continuity test

The fuse may be faulty.

Please contact support with:

• Photos of the fuse
• The multimeter test result

If the fuse tests normally

Continue to Step 2.

If you are not comfortable testing the fuse

Stop troubleshooting and contact support.

Step 2 – Check Battery Voltage

This step requires a multimeter and further electrical inspection. 

Measure the battery discharge voltage.

If the battery voltage is only a few volts or there is no voltage output

Further inspection is required.

The scooter may have:

• A battery fault
• Battery protection mode activation
• A controller-related charging issue

Please contact support with:

• Battery voltage readings
• Photos/videos of the battery connections
• Details about whether the scooter recently stopped charging suddenly

If the battery voltage appears normal

The issue may involve:

• Charging port wiring
• Charger output
• Internal charging components

Contact support for further diagnosis.

Charger Red and Green Lights Flash Alternately

This section applies if the charger flashes red and green after being connected to the scooter. 

Step 1 – Test the Charger Without the Scooter Connected

Disconnect the charger from the scooter and check the charger indicator light again. 

If the charger still flashes red and green

The charger may be faulty.

Please contact support with:

• A video showing the flashing lights
• A photo of the charger label

If the charger behaves normally when disconnected

Continue to Step 2.

Step 2 – Check for Motor Resistance

Carefully rotate the front and rear motors by hand and check for unusual resistance. 

If a motor has strong resistance

Do not continue riding the scooter.

This may indicate a controller issue.

Please contact support with:

• A video showing the wheel resistance
• A video showing both wheels spinning
• Details about any recent crashes, water exposure, or electrical issues

If the motors spin normally

Continue to Step 3.

Step 3 – Inspect Charging Port Wiring

Disconnect the charger from power before continuing. 

Inspect the charging port wiring for:

• Detached red or black wires
• Exposed wiring
• Signs of shorting or melting 

If wiring damage is found

Do not continue charging.

Contact support with clear photos of the damage.

If the wiring appears normal

Continue to Step 4.

Step 4 – Battery May Require Further Inspection

If:

• The charger works normally when disconnected
• The motors spin normally
• The charging port wiring appears normal
• The charger still flashes red and green

The battery may require further inspection. 

Please contact support and provide:

• Charger light behaviour video
• Battery voltage readings if available
• Photos of the charging port area
• Photos of the display

Scooter Only Charges While the Motor Is Spinning

This section applies if the scooter only begins charging while the wheel is spinning or the motor is running. 

Step 1 – Observe the Charger Light While the Motor Is Running

Lift the rear wheel safely off the ground before testing. 

Start the motor while the charger is connected and observe the charger light.

If the charger light turns red

This may indicate a battery-related issue.

Please contact support with:

• A video showing the test
• A video of the charger light changing colour

If the charger light stays green

The issue may involve:

• Charging wiring
• Charging port faults
• Charger faults 

Continue to Step 2.

Step 2 – Inspect Charging Wiring

Inspect the wiring between:

• The battery
• The charging port
• The charger connection 

If visible wiring damage is found

Do not continue charging.

Contact support with clear photos of the damage.

If no visible wiring damage is found

Continue to Step 3.

Step 3 – Further Electrical Testing Required

Additional voltage testing may be required to determine whether the issue involves:

• The battery
• The charging port
• The charger output 

If you are not experienced with electrical testing, stop troubleshooting and contact support.

Please provide:

• Charger behaviour video
• Photos of the charging setup
• Any voltage readings already completed
