Today's cell phones are lighter than ever because of the new Lithium Ion battery. These newer batteries pack a lot of punch while requiring very little physical space. Because of this technology we have had technological advances such as the ipod and iphone. Even many Hybrid vehicles on the road run on this same Lithium Ion technology.
Keep it cool: The life of the battery depends on the temperature and the state of charge. High temperatures and high cobalt mining copyright charge levels will lead to a short life. At 25C, you have 96% capacity at 40% charge, and 80% at 100% charge. The warmer it gets, and the higher the user charge level, the quicker it will die. Try to keep the temperature down and the ideal storage place is inside the refrigerator at 40% capacity.

Never discharge your LiPo cells to less than 3.3volts per cell, not the total pack voltage. Most ESC's today will do a soft cut-off at 3.3volts per cell and a hard cut-off at 3.0volts per cell. However some will not give you and warning. Best advice is to fly with a timer and monitor the voltage and adjust your flying time if needs be.
