I see some post about getting 6 min flight time out of the 450 battery's? Mine come down at 3.7-8 V per cell stopping at 5 minutes? And they are 460 mAh? Also do you leave your battery's charged ahead of time to go flying? I use to,but left them too long,and had cells "puff" after 2 weeks.
Now I charger them right before I go out,to the field. It would be nice to charge them the night before,and save some time getting ready. So how long, is too long,to leave a pack charged?
