Quadcopter battery time calc full#
Table 4 lists a variety of batteries with different capacities and their corresponding flight times at full and half discharge rates.Īfter researching the many different batteries available on the market, a Blue Lipo 1800 mAh 15C battery was chosen. Since there are a total of 4 motors, the total maximum drain of the battery will be 40 amps. The Turnigy 2730 Brushless Motor has a maximum amp rating of 10 amps. The example calculation below shows that an 8A drain on a 2000mAh battery will maintain charge for 15 minutes. Flight time is given in Equation 10 below. Flight time, which is directly proportional to battery capacity, can be found by dividing battery capacity by the amount of amps being drawn from the battery. Before we fly our quadcopter for the first time, it is a good precaution to make sure that all of the sensors onboard the KK2.1 are functioning correctly. Quadcopter flight time calculation Determine the maximum discharge of the battery. The capacity of a battery is rated in milliamp-hours (mAh).įor this project, flight time will be analyzed to determine the appropriate battery. We’ve been working hard programming all of the many settings in the KK2.1 needed to optimize the flight performance of our SK450 Dead Cat quadcopter.For example, a 1C battery can handle a current that would take an hour to fully discharge and a 2C battery is capable of being discharge in ½ an hour. Current is rated in C’s which is the maximum discharge rate of a battery.(NB: discharging a LiPo battery below 3V/cell will make it un-chargeable.) Unless you have 'OPTO' ESCs you will find that your ESCs all have BECs and will feed 5V on the red wire to whatever they are connected to. Each cell of a LiPo battery has a nominal voltage of 3.6 volts and is fully discharged when each cell reaches 3.0 volts, and a battery usually contains 1 to 3 cells. For 5V devices like servos, radios, and Arduinos you use a Battery Eliminator Circuit (BEC) which will regulate the battery voltage down to 5V.
The following is general information about LiPo batteries: The popularity of LiPo batteries is due to their large capacity, light weight, and excellent discharge capabilities.

The most commonly used type of battery in the hobby field today is Lithium Polymer (LiPo), and this type was chosen for this project. If you're wondering how to extend the flight time of your quadcopter, you're in the right place: this drone flight time calculator lets you experiment with relevant parameters to find the best combination for your drone.
