Am I doing something wrong.

I'm trying out both the dual and the tri cell, and I'm having problems getting much of a run time. I'm only running 2-3 minutes run time out of it with a 2.2 motor. It seemed like It was lasting longer at first, but I wasn't timing the run-time.

I'm running a 4.5 volt DC adaptor, 600mAh, and running through the calculations, this should take about 4 minutes to charge fully. Am I over or undercharging?

How can I extend the runtime?
