Li-Po batteries are known for their high-power and durability, it is light in weight but the question is why Li-Po batteries are most commonly used in quadcopters? We will find out the answer below.
In recent times, there is immense demand fashioned for multi-rotors, quadcopters, drones alike which are electronic devices capable of flight with simple control mechanics. Often these electronic devices are affixed with modern action cameras which in these times of domination of social media are wildly in demand for documentarians, videographers, photojournalists, scientists all alike.
The intriguing devices have grown exponentially in demand which is extremely alluring to people of all ages.
In this article, we will explain why Li-Po batteries are commonly used in multirotor.
The range of these flight possible aerial electronic devices derives their names from the number of motors they are constructed with during manufacturing. These are your tri-copters, quad-copters, hexacopters, and so on. The design and manufacture of these devices are simple as well as their functional operation which mainly includes motors, blades among others. In recent times, the technology from modern helicopters has been transferred to these many trendy devices which are that of the coaxially rotating motors which simply put are two pairs of rotating blades making them more powerful devices.
The multirotor like most electronic devices are ever so dependent on the batteries they are configured with for the source of their power. The range, power, altitude level and time span of flight are directly influenced by the power and capacity of the battery they are built them with.
The technological advancements in the science and manufacture of batteries have been immensely exponential. The range of batteries is wide in shapes, sizes, types, capacities, voltage levels, chemical compositions among others. The amount of time your flight device will stay afloat depends directly on the battery.
In recent times, the progress in the field of lithium-based batteries has received global recognition and even achieved Noble Prize for the inventors. In the design and manufacture of multirotor devices, the lithium polymer or popularly known Li-Po batteries are much preferred primarily for their ability to retain power at a consistent level.
Battery cells and voltage:
The ratio of cells and voltage is often printed on the battery packets by most brands represented often by letters ‘S’ & ‘V’ for cells and voltage respectively. A 7.4 V 2S LiPo battery means that the battery has 7.4 volts and 2 cells.
Information for appropriate selection in simple terms is that the higher the numerical figures mentioned the more powerful the battery. The range of lithium polymer batteries in terms of voltage ranges from 3.7V to 22.2V.
The capacity of the battery such as a 3S LiPo battery directly influences the flight span of your device. The higher the voltage, the greater the number of cells the higher is the capacity of your battery but conversely the heavier will be the weight of the battery. So in lieu of this information depending on your need one can choose an appropriate battery.
The discharge rate is also known as C-Rating and is represented by the letter ‘C’. The discharge rate denotes the rate at which the battery discharges its consisted power after it has been fully charged to its fullest power level. The higher the C-Rating the longer will the battery hold its power.
The discharge rate can be a very important factor when it comes down to the flight span tenure of any multirotor electronic device. So, depending on the nature of need one can choose a battery with the lowest discharge rate ratio. In the consumer market, most multirotor drones are configured with 14.8V 4S LiPo battery.
