Batteries taking long time to charge

[DoubleEagle1]

I was having the same issue, so I switched and plugged in the smaller and thinner usb cable and immediately I noticed the the flashing green lights started charging faster. I thought the thicker cable to the power source would charge quicker but not the case. Try this and you’ll notice the difference.

Yes, the thicker usb cable is for charging your RC. You can use it to charge your batteries if you require a nice slow gradual charge.
