How can you diagnose and fix drone power supply issues?

1 Check the battery

The first thing you should do when you encounter a power problem is to check the battery. A low or depleted battery can prevent your drone from taking off or staying in the air. You can use a multimeter or a battery tester to measure the voltage and capacity of your battery. If the voltage is below the recommended level for your drone model, you need to recharge the battery. If the capacity is significantly lower than the rated value, you may need to replace the battery.

5 Check the motors

The motors are the muscles of your drone. They spin the propellers and provide the thrust and stability for your drone. A damaged or worn-out motor can cause your drone to lose power, vibrate, or tilt. You should check the motors for any physical damage, such as dents, bends, or debris. You should also check the performance and temperature of the motors. You can use a tachometer to measure the speed and a thermometer to measure the heat of the motors. If you find any abnormal readings, you need to clean, repair, or replace the motors.

6 Check the propellers

The propellers are the wings of your drone. They create the lift and thrust for your drone. A broken or unbalanced propeller can cause your drone to lose power, wobble, or drift. You should check the propellers for any physical damage, such as cracks, chips, or bends. You should also check the balance and alignment of the propellers. You can use a propeller balancer to measure the weight and a ruler to measure the distance of the propellers. If you find any uneven or misaligned propellers, you need to trim, adjust, or replace them.
