Hi so I got this hoverboard from the name HoverTech and I m having some problems getting it started. So when I first got it I turned it on and tried riding it but it just started beeping. So I plug it into the charger and the led is red. I wait for it too turn green and unplug it (took about an hour). Then I turn it on and try to ride it but it just starts beeping and neither of the motors turn on, plus the battery symbol is a full green batter (not blinking). Any help?
