Charging
1. Make sure to turn off the battery before charging to avoid power port damage. Make sure the battery
level is 95% or lower before charging. If the battery level is higher than 95%, discharge the battery until
the battery level is 95% or lower. Otherwise, the battery will not charge.
2. The battery is designed to stop charging when it is fully charged. However, it is good practice to monitor
the charging progress and disconnect the battery when fully charged.
Disposal
1. If the battery is disabled and the battery cannot be fully discharged, contact a professional battery
disposal or recycling agent for further assistance.
2. If the battery cannot be powered on after over-discharging, dispose of the battery.
Motors
To avoid component malfunction, serious injury, and property damage, observe the following rules:
1. Make sure that the motors are securely mounted and rotating smoothly before powering on.
2. DO NOT attempt to modify the structure of the motors.
3. DO NOT touch or let your hands come into contact with the motors, motor mounting plates, or inside
of the Mecanum wheel immediately after powering off the robot.
1. Make sure there are no foreign objects inside of the motors.
2. Make sure the connections between all the motors and the motion controller are stable.
3. If the motor cannot rotate freely, immediately power it off and check.

and that they are functioning properly.
