Brand New Rage VEI Won't Run 3S Lipo?

[Average Joe Nitro]

Hello everyone! I just purchased a new Kyosho Rage VEI and bought 2 Venom 2100 Mah 3s lipo batteries with it. When I put it in the motor flashes green but does not beep like it does when I put in the NiMH that it came with. I know I have seen videos on YouTube of this thing running 3s.

The steering works but the car is dead in the water. Won't move at all. I have verified that the battery is indeed charged. The voltage is at 12.15 volts. Has anyone had a problem like this or can at least help me troubleshoot this out? I can't find help anywhere and I sure hope I haven't wasted my money on these lipos!

Thank you very much for your time!
