What is the reason why the drone lithium battery is so expensive?

The first thing is characteristic, the drone is not getting rid of the gravity of its own, and thus, the net weight of the battery is high, and the bulk battery volume will cause a net weight, and thus only the same volume is relatively light, a relatively light polymer lithium-ion battery. It can meet the requirements, on the other hand, the unmanned aircraft is particularly high for the output power of the battery, and when the throttle pedal to the maximum rate is rapidly increased from the hover situation, the battery output power will rapidly increase, and several times the output power is better in a short time. promote.

Such an output power shift is only the polymer lithium ion battery can be considered. In fact, the 18650 battery can be used in series and in parallel, and the battery of Tesla electric car is 7000 18650 batteries in series and in parallel. Further, you can take a moment of power, this is very uncomfortable on an unmanned plane.

Thus, in terms of characteristics, only the polymer lithium ion battery can consider such use requirements. Naturally, even if the polymer lithium-ion battery is consumed on the unmanned airplane, it is very fast, and the Battle of 5800mAh, the battery, the kinetic energy is more than 89WH, and the kinetic energy under the 20000mAh mobile power is generally only Level 70WH, and that, a 5800mAh battery only has a 30-minute navigation time, and it is possible to imagine how much work pressure on the battery is, and the long-term polymer lithium ion battery is very fast, and the battery is very fast, and Quick charge and discharge in a short period of time will also cause the battery temperature to rise rapidly, which has prompted unmanned aircraft battery non-further safety maintenance. The unmanned aircraft battery of Dabin is called an intelligent navigation battery, which is due to the addition of a polymer lithium-ion battery, which has a large number of components on the battery.

First, in order to better maintain the safety of the battery, the switching power supply intelligent management system can carry out battery charging maintenance of the battery, which can be in the field of safety in the battery. Second, if the long-term full-time electricity of the battery will harm the battery life, the battery stores the battery life of the battery to store lithium-ion battery life, which can be fully charged and discharge, new increase in long-term idle conditions. Battery usage time.

This set of technical, very like Tesla Automotive Switching Power Supply Intelligent Management System. Thus, whether in terms of characteristics or safety perspectives, the battery used by the drone is not much higher than the 18650 battery usually used by the general mobile power supply, which also prompted its price expensive.
