A protection device for battery assembly includes a battery unit having multiple secondary Lithium batteries and the battery unit is electrically connected with a detection-control unit which is electrically connected to a by-pass which is a charge/discharge circuit. The detection-control unit has a voltage detection circuit and a micro controller unit to detect output voltage of the battery unit. A receiving device is electrically connected to the detection-control unit to receive wireless signals from a remote controller. The receiving device transmits signals to the detection-control unit. An emitting device is electrically connected to the detection-control unit to send signals to the remote controller when the battery unit has abnormal voltages. The battery unit is monitored and controlled by the detection-control device.
