How long does a drone battery last??

When using electric drones, one of the most concerned issues is about the battery last and the endurance of the drone. How long your drone’s battery will last in the air depends on the model. The top-class industrial drones have batteries last for at least 1h-2h, mid-class industrial drones batteries will last 30mins-1h. If your industrial drone is small in size, perhaps its battery will only last 20-30mins or less. And if you are interested in how to calculate flight time, you can first look at the method of calculating flight time.

How to calculate battery flight time for a drone?

Here is a formula below:

Flight time(mins) = Battery Capacity (AH) / ( Motors Number x Motor Current(A) ) x60 x 0.8

Note: The Motor Current needs to refer to the current corresponding to the thrust in the motor data table.

?

For example:

A quadrotor drone? ? ? ? ??

6S 30ah battery*1 PC

Take-off weight 4.25kg

?

1. Calculate the thrust of each motor:

4.25/4=1.06 (kg)

2. Find the corresponding current in the motor parameter table according to the calculated thrust and the throttle is best at 50%-60%.

3. The formula is used to calculate the flight time

Flight time = 30 (ah) / ( 4x 7.98 (A) ) x 60 x 0.8

Flight time = 45mins

?

Actual flight time may be affected by flight conditions (such as wind speed, temperature), flight patterns (rapid acceleration or crash stops, etc.), and loads (cameras, etc.). Therefore, the calculation is only an estimate.?Pay attention to the consumption of battery power during the actual flight to ensure that the drone flies within a safe range and returns in time.
