They are all lithium batteries. Why are drone batteries so expensive? This is because the polymer lithium-ion batteries used in drone batteries are different from the 18650 batteries used in power banks. The reason why they are much more expensive is that compared to other digital devices, drones have more stringent requirements for drone lithium batteries, so the price will rise sharply.
First of all, performance. UAVs need to overcome their own gravity to do work, so the weight requirement for the battery is high, and increasing the battery capacity will lead to an increase in weight. Therefore, only polymer lithium-ion batteries with lighter weight under the same capacity can meet the needs. On the other hand, UAVs have particularly high requirements for battery power. When the throttle is quickly increased from the hovering state to a certain speed, the battery power will increase rapidly, and the power will increase several times in a short period of time. Only polymer lithium-ion batteries can meet such power changes. In fact, 18650 batteries can also meet such requirements through series and parallel connection. The battery of a car is more than 7,000 18650 batteries connected in series and parallel, so that it can withstand instantaneous high power requirements, which is obviously not suitable for drones. Therefore, in terms of performance, only polymer lithium-ion batteries can meet such usage requirements.
Of course, even polymer lithium-ion batteries wear out very quickly on drones. A 20,000mah power bank generally holds just over 70Wh of energy, and a 5,800mah battery can only support 30 minutes of flight time. You can imagine how much pressure is put on the battery. Polymer lithium-ion batteries wear out very quickly in this working environment for a long time, and rapid discharge in a short period of time will also cause the battery temperature to rise rapidly. All of these require further protection of drone batteries.
UAV batteriesare all called intelligent flight batteries, because in addition to polymer lithium-ion batteries, the battery also has more components. First, in order to protect the long-term operation of the battery, the power management system can charge and discharge the battery to protect it, and can always keep the battery working within a certain range. Secondly, if the battery is fully charged and left idle for a long time, it will affect the battery life. The Jinchi drone battery has built-in battery storage self-discharge protection, which can automatically discharge when left idle for a long time, extending the battery life. This set of technology is a bit like a simplified version of Tesla's power management system.
Therefore, whether from the perspective of performance or technology, the battery requirements for drones are higher than the 18650 batteries used in ordinary power banks, which also makes them expensive.
In recent years, the use of drones in the civil field has continued to expand, especially in agriculture, forestry, electricity, security, surveying and mapping, and patrol lines, which are widely used in the civil field. At the same time, the drone battery market has also prospered, and various drone battery brands have emerged.
Jinchi meets the standards in the production of drone batteries and has received a lot of support. If you choose drone batteries, come to Jinchi Technology.
