I know LiPo batteries are supposed to charged to a specific voltage per cell if the batteries are to be stored. How long of a period of time is considered "stored"? How long of a period of time is it okay to keep a LiPo battery charged? If I came in one evening from running and fully charged my batteries would it hurt them to sit charged overnight and ran the next day or the day after? If I run my batteries today should I leave them discharged overnight and charge them the next day or charge them back up the same night?
