Let's see. You have 2 P4s. I believe the fwd voltage of both is around 4v, so I'm just going to assume that for now b/c I'm not looking it up right now.
If your battery solution is going to be something like 6v (4AA as you said)... hmm... that will always be a waste of power any way you do it, parallel or serial... unless you use some kind of driver.
