Battery life has become shorter, this is a problem that many drone users encounter, but what are the specific reasons why the battery life has become shorter?
1. External reasons lead to the shortening of the battery use time
(1) Problems with the drone itself
There are two main aspects of this, one is the drone itself, such as the aging of the drone connection line, the resistance of the electronic components increases, it is easier to heat up and consume power, and the power consumption becomes faster. Or encounter weather gusts and other reasons, wind resistance is too large, etc. lead to the drone range time becomes shorter.
(2) Changes in use environment: low or high temperature effects
Batteries are used in different environmental temperatures, their discharge efficiency will be different.
In low temperature environment, such as -20℃ or below, the internal raw materials of the battery are affected by low temperature, such as electrolyte is frozen, the conductive ability will be greatly reduced, coupled with other raw materials are frozen, the chemical reaction activity decreases, which will lead to less capacity, the performance of the situation is that the battery use time becomes shorter, poor or even can not be used.
If the temperature is too high, it will accelerate the aging of the internal materials of the battery, the resistance will increase, the same will make the battery capacity becomes smaller, the discharge efficiency is greatly reduced, the same effect is the effect of the use of time becomes shorter or can not be used.
2. The battery itself shortens the time of use
If you buy a new battery, in the use of a shorter period of time after the battery found that the durability of the time has become shorter, this may have the following reasons:
(1) Aging of raw materials used in the manufacture of batteries
Battery in the work, the material in the chemical reaction cycle is easy to aging or expansion, etc., resulting in increased internal resistance, capacity degradation, the direct performance is fast consumption of electricity, discharge weak and no force.
(2) Inconsistency of electric core
High-power UAV batteries are composed of many electric cells by means of series and parallel connection, and there will be capacity difference, internal resistance difference, voltage difference and other problems between the electric cells. With the constant use of the battery, these data will become larger, which will ultimately affect the capacity of the battery, that is, the battery capacity will become smaller, resulting in a natural shortening of the actual endurance time.
3. Improper use of the battery caused by the use of time becomes shorter
The battery is not used in accordance with the instructions, such as frequent overcharging and overdischarging, casually discarded, resulting in internal deformation of the battery or loose material inside the battery core, etc. These improper use of behavior will lead to accelerated aging of the battery material, increased internal resistance, capacity degradation and other issues, the battery time naturally becomes shorter.
Therefore, there are various reasons why drone battery time becomes shorter, not necessarily all of them are the cause of the battery. For the drone range time becomes shorter, it is necessary to find out the real reason and analyze it carefully in order to recognize and solve it correctly.
