Scorpion Backup Guard II power management board for ESC in ultra small foot-print and super lightweight.

The new Backup Guard II is much more flexible and robust than its predecessor, with many new features!

One great feature is the Charge Mode.  This means that the Backup Guard II can charge up the attached battery while it is operating and with balancing!  The charge rate is at a safe 0.5A.  This means you will no longer need detached battery and charge it on a charger again.  Use a small size 2S Li-Po battery and just attach it to the JST-XHR connector (the balance connector on the battery) on the Backup Guard II.

The Backup Guard II provides a smooth DC 5V with 10Amp Output when there is trouble with ESC's BEC.  The power provided is sufficient to land your aircraft no matter it is a airplane or a helicopter.

The Backup Guard II now comes with 4LED indicates states.
