Thoughts on battery care. If you want to get the best performance and greatest number of flights possible from your batteries, limit your flight times to under 2:30 secs (if your flying hard). It only takes one "too long" of a flight to damage a battery to the point that it will no longer perform as new and worse it will continue to rapidly degrade from that point on.
