Can the battery life of a drone with two batteries connected in parallel be doubled?
If the capacity of the battery increases under a certain power consumption, the device should be able to run for a longer time. In order to have a stronger UAV battery life, theoretically it is also possible to increase the capacity of the UAV battery. So can the battery life of two battery drones be doubled in parallel?
In fact, the answer is no. Below we will explain the reason theoretically.
When two drone batteries are connected in parallel, if the voltage difference between the two batteries is within 20mV, the capacity can be adjusted; if it is not or there are some conditions, there will be different results:
1. When the voltage difference between the two UAV batteries is too large, the capacity may remain the same or increase, or even reduce the capacity. The battery pack will think that the UAV’s battery life will be It may not increase, but decrease;
2. When using the same batch of the same drone battery from the same manufacturer in parallel, the battery capacity is doubled at this time, but the drone’s endurance is impossible To achieve the doubled effect. Because the overall quality of the drone at this time has increased, additional energy is needed for support, so the drone’s battery life cannot be doubled.
3. When using batteries from different manufacturers in parallel, at this time, due to the differences in the production technology level and material formula of each manufacturer, the capacity of the batteries after parallel connection may be more than doubled or lower than Times. The difference in electrical conductivity in the battery of colleagues will reduce the service life of the UAV battery.
4. When using batteries from the same manufacturer and using different batteries from new and old ones, the capacity of the batteries after parallel connection may be more than doubled or less than doubled. The difference in electrical conductivity in the battery of colleagues will reduce the service life of the UAV battery. Because the old battery materials will undergo a certain degree of change.
The above is the reason that using two parallel unmanned batteries cannot double the UAV's battery life.
