Lifespan of 300 discharge/charge cycles, takes between 60 and 90 minutes to charge depending on starting level, smart chip so it does its own balancing and low- and high-voltage protection internally, if you run it down to between 15 and 20% you get 20 minute flight times without thinking about it, 25 minutes if you don't do too much full speed work and hovering/power climbing, etc.
