How does Scorpion Backup Guard II work?
When activated, the Scorpion Backup Guard II monitors whether that the BEC
output voltage on the helicopter or airplane is 5.5V or higher. If the
Scorpion Backup Guard II detects a BEC failure has occurred, it will take over
and continue to power the radio system thus allowing time for you to land your
helicopter or airplane safely.
LED Indicator Lights
There are two sets of LED indicator lights on Scorpion Back Guard
II.
The colors of the LED lights indicate the status/condition of Scorpion Backup Guard II. To operate, the switch of Scorpion Backup Guard II has to be ON.
LED Light # / Color| Status/Condition| Control systems are
powered by:

Connect your Scorpion Backup Guard
Connect the DC 5V Output connector to an empty socket on the receiver. If all the sockets are being used, use a Y-harness wire to connect to any servo output socket.
Warning:
DO NOT plug the Scorpion Backup Guard II’s DC 5V Output connector into the
S-Bus channel port. This will drain the Backup Guard II battery without
charging.
DO NOT plug the Scorpion Backup Guard II’s DC 5V Output connector into any
socket that is NOT recommended by the receiver or gyro manufacturer (e.g,
telemetry). Please refer to your receiver and gyro instruction manual for
details.
Using your Scorpion Backup Guard
Charge up the 2S Li-Po battery using a proper Li-Po charger*. Connect the 2S Li-Po battery to the JST-XHR connector on the Scorpion Backup Guard II. Check and make sure the DC 5V Output connector is securely connected to the receiver/gyro.
- Although you can connect the 2S Li-Po battery to the Scorpion Backup Guard II and let the main battery charge it when operating, charging time maybe lengthy and depends on the status on the 2S Li-Po battery.
The charging rate is 0.5A.
Power-up sequence:
Main Battery ON >> Scorpion Backup Guard II ON
Power-down sequence:
Scorpion Backup Guard II OFF >> Main Battery OFF
Power off Scorpion Backup Guard II first then you can power off the BEC system
or ESC after the flight. Always turn Scorpion Backup Guard II ON last, and
turn OFF first, to identify whether your BEC is functioning properly.
Maintenance for your Scorpion Backup Guard
Because of the DC 5V is a one-way output, whenever the main power unit output
voltage is higher than DC 5.5V, the Scorpion Backup Guard II will not be
drained by the power consumption of the radio system.
For maintenance, perform routine checks on the balance and health of the 2S
Li-Po battery.
If you are not planning to use the Scorpion Backup Guard II for a long period
of time, please disconnect the 2S Li-Po battery and safely keep the battery’s
charge level at 50% charged. Remember to charge up the 2S Li-Po battery to
8.4v before you use it.
