quad hardware = lithium polymer battery (research)

the quadcopter drone needs a power source to juice up the onboard electric equipment. A lipoly battery pack is used due to its high capacity and low weight. Calculation is made to predict the flight time available for the quadcopter with selected capacity of the battery. This needs to be balanced as a larger capacity means the battery need to be bigger and heavier. It is recommended by a technical expert that a 4 cell lipoly battery pack of 4500mah capacity to be used for the above quadcopter configuration.
