For aerial photography work or FPV flying which the motors will have to spin faster, and thus pull more current. Obviously this quadcopter battery calculator is a very simplistic calculator base on steady hover.

Make a conclusion for quadcopter flight timeįor instance, I have a lipo battery 3s 3300mAh, I calculated the average amp draw of quadcopter to be around 20 amps, and I am making an assumption that 80% of battery capacity will is used, then the quadcopter flight time is 7,92 minutes.

I found a formula for quadcopter flight time calculator Quadcopter flight times (Battery Capacity Battery Discharge /Average Amp Draw)60 How about this calculator formula For instance, If have a lipo battery 3s 3300mAh, I calculated the average amp draw of quadcopter to be around 20 amps, and I am making an.

Then your quadcopter Average Amp Draw is 20AMPS ( 20AMPS =4motors * 500g/100g per 1amps) Īn other way to work out the average amp draw, buy a smart lipo battery which will record lipo Amp Draw when quadcopter move on or steady hover in the sky, this calculator much more accurate than the frist one. After you buying a drone, you will consider how to increase your flight times. if your quadcopter take 2000g to flight, each motor will have to produce 500g (500g = 2000g / 4 motors) of thrust in order to hover. An other thing is the parameters of quadcopter motor, Read your motor instructions, you have to know how many amps one motor will be draw to produce 100g of thrust? This is the key points in the calculation of Average Amp Draw.įor example, If you know each motor draws 1 amps to produce 100g of thrust. How to work out Average Amp Draw?īefore quadcopter battery calculator you work out the average amp draw, you have to know two things, one is about your carrying weight of your quadcopter which include battery weight. For instance, 1.8Ah*0.8=1.44A (effective capacity).īy the way, quadcopter flight times calculator base on the true battery Capacity or the non-oversized in capacity. In respect of this, it’s common practice to not discharge your LiPo batteries below 20% mAh during flight In other words, the effective capacity is only 80% that can be used during flight time. Battery Discharge:įrom lipo battery warnig will let you know that be too dangerous and be permanently damaged when voltage levels become lower then 20% and fully discharged. For calculator you have to take the battery’s capacity in amp hours, to convert from mAh to Ah, battery capacity divide by 1000. But today we are not to discuss the matter. In fact As the battery gets larger, the increase in flight time becomes ineffective, because of the weight of battery. Choose the right battery is good for increasing your quadcopter flight time, Please check out: Best Drone Battery Choosing Guide Battery Capacity:Īs we know, Bigger lipo battery can be powered more energy.
