OK, now say you are using a motor that draws 150mA when driving a small motor cycle. If your battery has a capacity of 300mAh, it will theoretically power your motor for 300 mAh/ 150mA == 2 hours. So naturally, if you are using 6x 2100 mAh 1.5V AA batteries, your motor will last 2100 mAh/150mA == 14 hours.
This is theoretical, of course. If you are going the route of the 9V battery block, which is nice and compact and light, I would recommend using rechargeable batteries, or you'll end up spending a fortune on these.
Thanks, I think I understand now. Would you still go this route? And I didn't see an answer on my power supply post above your first one.
