Battery problem???

Ok, so I'll be cruising along, and sometimes the battery light and ebrake light will begin to blink simultaneously. If I turn the heat on, it will decrease the blinking speed, but they will still blink. It usually starts happening after I've been driving the car for awhile. The dash lights soon begin to blink as well, after these two lights begin blinking, so I'm guessing it's an electrical issue? Anybody know what the problem is? I was thinking maybe the battery is going bad, but I just got it in December...
