Is there a difference in run time/battery life between a charged battery that just came of the charger, and one that was charged 5 to 8 hours before. Also is it bad to leave a charged battery lying around for 5-8 hours. I'm new to these lipo battery pacs, they take toooo long to charge. I decided to charge the batterys at work and use them at night when I get home. Will charging that far in advance mess up the battery pacs? So far I had 3 sucessful filghts with no issues.
