Over-discharge Protector
The lithium battery will be permanently damaged if the battery’s capacity has been completely
discharged. Therefore, Smart Chair is equipped with an over-discharge protector. When the lithium
battery is running out, the protector will cut off the circuit automatically and the controller will stop
working.
When the lowest level red LED light on the battery level indicator flashes, it means that the batteries
need to be charged.
When there is no red LED light on battery level indicator, it means that the batteries must be charged
within 2 hours immediately. If not, the battery may not be activated permanently.
The charging time after over-discharge takes 10-12 hours.
When the lowest level
red LED light flashes,
the batteries need to be
charged
Over-current Protector
Smart Chair is also equipped with an over-current protector. If the current supplied to the motor is
too high, the over-current protector will cut off the current supply. If crossing over a slope over 12
o
or the load is over 330 lbs or the motor rotation is jammed, the over-current protector will be activated
and the chair’s control will cut off the circuit to prevent overcurrent and overheating of the motor.
The red LED light on the control panel will flash and the buzzer will sound.
Battery Socket Cleaning
• Check the battery pack and the positive and negative poles for any corrosion. If any, clean
with battery cleaning tools, steel brush or medium sandpaper.
• When cleaning, Keep tools and other metal objects away from battery terminals. If contacted,
short-circuit or electric shock may occur and cause bodily injury.
CAUTION
Do not allow the acidic substance inside the battery to come into contact with your skin, clothes or
other items. The substance is extremely hazardous and may cause serious burn. When contacted,
immediately flush your skin with cold water and seek medical attention.
