Flashing red light on speed passion pro

[Jimbob2911]

Evening,

Just starting out with electric cars. Just finished building b44.1 with speed passion pro and 7.5 turn speed passion sensored motor.

Everything seems to work ok but the speed controller red and orange light start solid but once I accelerate once the red light just constantly flashes. The orange stays solid.

I am running lipo 2s 5100mah which are fully charged. The book says red flashing light means low voltage but doesn't seem like it is this due to fully charged battery.

Any ideas?

Thanks James
