In 2012 Scorpion Power Systems released the first generation of the Scorpion Backup Guard, and its function was to help save model airplanes and helicopters if they happened to lose power from the ESC/BEC. After many years, an updated design was needed to meet the ever changing demand of customers and the market! Today, Scorpion is proud to introduce the next generation of this product, the “Backup Guard II." This New Backup Guard II is much stronger than its predecessor, with many new features as well. One new extraordinary feature is the Charge Mode. This means that the Backup Guard II can charge up the Backup Battery, with balancing, while it is operating. Charging rate will be 0.5A. This means you will no longer need to charge the Backup Battery ever again!
The Backup Guard II is now only the “Power Board” and you can connect your own size of 2s Lipo with JST-XHR Connector. The Backup Guard II provides DC 5V with 10Amp Output, which is enough to land the aircraft if the ESC/BEC has some failure.
The Second-generation of Backup Guard II has 4 LED that will indicate the status.

Scorpion Backup Guard II (Power Board)
This unit appears to be suited for BECs that produce at least 5.5 volts or more. It does not work properly for your typical 5 volt BEC. The reason is that anytime it detects less than 5.5 volts, it goes into backup mode since it assumes the BEC has failed. I hooked it up to my receiver that was getting 5.3 volts from a fully functional BEC. This unit assumed that was a failure (less than 5.5v) and the red LED indicating a discharging back up battery stayed on full time. The 2S back up battery I was using was at storage voltage and could never charge in this condition. If your BEC produces more than 5.5 volts, this unit would be fine. None of mine do, so I returned it and purchased the Optipower Ultra Guard. Optipower takes a snapshot of your BEC voltage at initial power up and sets the backup intervene point at .5 volts below whatever level that is. The Scorpion unit simply looks for anything less than 5.5 volts.
