More and more enthusiasts or professionals are eagerly awaiting the moment to release their beloved drone into the air every day. There are on the market of all sizes and for all budgets. This mechanical prodigy would not be possible without the beating heart of the aircraft: the 4s LiPo battery. So let’s see what it is and what its strengths and weaknesses are.
LiPo (Lithium Polymer) batteries, developed in the former Soviet Union, have revolutionized the world of electric aviation. Unlike the old lithium-ion cell batteries, they do not need any metal container and are extremely light and versatile. The secret of its success is the ability to store a significant amount of energy in very little space. There are now hundreds of models of LiPo batteries applicable to the most varied uses. The 4s lipo battery is the best among them.
Although, as mentioned, 4s LiPo batteries are extremely versatile, at present, they show a not insignificant limitation for those who wish to fly the drone for hours and hours without interruptions: the battery life. So far, it is, unfortunately, a dream (but never say the last word considering the speed of technological innovation in today’s world).
According to the latest statistics, the maximum duration of the most “powerful” and expensive drones does not exceed 27/28 minutes. The average of the standard models is about 15/20 minutes. If we then go down to “cheap” categories, we can get to just 5/7 minutes.
While it is true that the LiPo battery lasts less than you hope, with a few simple tricks, you can maximize its resistance. Let’s see what they are:
Apart from the limited duration, another important limitation – sometimes dangerous – is the flammability of 4s LiPo. There are numerous cases in which incorrect use has generated spectacular combustion. No fear! By following these easy steps, the risk is minimized:
