Can two batteries be connected in parallel to double the drone's battery life?

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 two unmanned When the battery pressure difference is too large, the capacity may remain the same or increase, or even reduce the capacity. The battery pack will think that at this time, the drone battery life may not be added, but will decrease; 2. When using the same manufacturer After the same batch of the same drone batteries are connected in parallel, the battery capacity is doubled at this time, but it is impossible for the drone's endurance capability to double. At this time, the overall quality of the drone has been increased, and additional energy is needed for support, so that the drone’s battery life cannot be doubled. 3. When using batteries from different manufacturers in parallel, at this time, due to differences in the production technology level and material formulations of each manufacturer, the capacity of the batteries after parallel connection may be more than doubled or less than doubled. The difference in electrical conductivity within the colleague's battery will reduce the service life of the drone's battery. 4. When using batteries of 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 within the colleague's battery will reduce the service life of the drone's battery. Because the old battery materials will undergo a certain degree of change. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
