While doing circuit training, a student pilot can do 5 training circuits of 6 mins each using 30 minutes of battery. They'll probably be so overwhelmed and fatigued afterwards (well, I was anyway) that their day's training is over. That's five or six exhausted student pilots per exhausted battery. :)
