They are at least 8aH batteries (I believe so). I also tested the motors and it seems they draw 3A or so. Also, I'll probably swap them with fresh batteries in between the two 10 minute intervals to play it super safe. The main thing is I want to make sure that the motors won't burn out. Do you think I should add a cooling fan or add vent holes?Then you're probably fine. Those motors won't burn out on stock discharge capability from D-cell alkalines powering them at stock voltages. I would monitor the batteries though as they may be drained by running that long.
