X-Star Battery - Getting a non-charging battery to charger

[Aerial Drone Architect]

Here is how I the new (used) batteries that I just purchased to charge. I hope this can help some of you get back in the air. Please use caution if you attempt to try this at home.........

Thanks for the video. I tried it and brought back a completely dead battery. I used a 9VDC
wall wart for low current to get a surface charge on the pack. It charged right up. Would
I trust the pack if I were flying over water or terrain that I couldn't cross? No, but it does
give me an additional pack to play around with locally.
