Default battery light comes on under heavy load

anyone experience this? i'm utterly confused as to why under heavy loads and high rpm the battery light comes on until i lift the throttle or the engine shifts n rpm drops. then the light goes off. also, as soon as the light comes on the voltmeter on the instrument panel drops to around 10-11 when it's usually around 13 volts...any ideas?
