BATTERY INSTRUCTIONS (CONT’D)
Over-discharge Protection Device
When the battery of the electric wheelchair is depleted, the battery over-discharge protection device will protect the
charger for excessive discharge. It is important to note that when the over-discharge protection device is activated
the maximum speed will be reduced. This is a built-in safety measure for your electric wheelchair.
Over-current Protection Device
The electric wheelchair is also equipped with an over-current protection device. If the current provided to the motor
exceeds its rating, an electronic fuse will disconnect the current. If the fuse is blown, while driving, the over-current
protection device will engage and the power to the rear wheels will stop. In this process, the fuse will cut off the
current, prevent the motor from being damaged by overheating.
