Connect the Ultra-Guard to your receiver (as it would be normally connected) and power on the receiver.
Don't fly it though.
The Ultra-Guard will suck quite a bit of power out of the battery as it charges.
Or, connect a 2S LiPo directly to the Ultra-Guard's connector. It will power on and start charging.
It will charge itself quite nicely.
The red LED will be blinking as it charges and will stop blinking when it is done
When you unplug the Ultra-Guard, it will still be powered on. Make sure you power it when you are done charging it
Believe 1/2 of what you see and none of what you hear.
Fake News will be the downfall of our Republic!
