People who are familiar with drones know that, for example, the price of a 10,000 mAh UAV battery Tattu is close to 1,000 units, while the commonly used 20,000 mAh charger only costs 1-200 yuan (such as the Xiaomi charger). Why is there such a big difference? Wouldn't it be better to use a 20000 mAh rechargeable battery?
This is because the lithium battery used in the drone is different from the 18650 battery used in the charger. Because they require more batteries than other digital devices, prices have skyrocketed.
From a performance point of view, the drone must overcome its own gravity to do work, so it has a high demand for battery weight and new battery capacity will lead to new weight, so only a light weight capability can meet the demand. On the other hand, drones have particularly high requirements for battery power. When the throttle valve is rapidly increased from hovering to the maximum speed, the battery power increases rapidly, increasing the power several times in a short period of time. This power change can only be met by polymer lithium batteries. In fact, 18650 batteries can also be connected in series and parallel to meet this requirement. Tesla's battery is made up of more than 7000 18650 batteries in series and parallel, which can withstand the instant high power demand and is obviously not suitable for drone use. Therefore, in terms of performance, only polymer lithium batteries can meet this demand.
Of course, even if the lost polymer lithium battery is very fast in the drone (uav) (uav), the 5800 mah battery can only support 30 minutes of flight time. You can imagine how much the battery is under pressure, and the polymer lithium battery works like this In the environment for a long time, the battery is very fast, and in a short period of time, the battery will be discharged quickly and the temperature will rise rapidly, so that the battery of the UAV needs further protection.
Therefore, the battery used by drones has higher performance and safety requirements than the 18650 battery used by ordinary chargers, which makes it more expensive.
GE UAV battery is famous for its high power ratio, large capacity, strong explosive power and other excellent performance, which fully meets the needs of UAV take-off. In addition, GE has also mastered a number of core technologies of lithium polymer batteries, with long battery life, excellent safety performance, low loss and long service life. General Electric currently has batteries for all drones.
