Why Are Diy Drone Battery Diy So Expensive?

The people who are familiar with the drone may know that a more than 5000 Ma diy drone battery sells for nearly 1000, and our usual charge of 20000 Ma is one hundred or two hundred yuan. Why is the difference so big? Is it longer to use 20000 Ma's rechargeable batteries to use on the drone, isn't it?

This is because of the difference between the 18650 batteries used by the drone and the power bank. Compared with other digital devices, the drone is more stringent on battery requirements, so prices will rise sharply.

First is the performance, the drone needs to overcome its own gravity to do work. Therefore, the weight requirements of the battery are higher and the capacity of the battery will increase the weight. Therefore, only the lighter polymer lithium-ion battery can meet the needs. Drones, on the other hand, have a particularly high demand for battery power. When the throttle is quickly raised to the maximum speed from the hover state, the power of the battery will be increased rapidly, and the power will be increased several times in a short time. Such power changes can be met only by the polymer lithium ion battery. As a matter of fact, 18650 batteries can meet such requirements through a series of parallel connections. The Tesla car's battery is more than 7000 pieces of 18650 battery strings in parallel so that it can withstand the instantaneous high power demand. However, it is obviously unfit for the drone. Therefore, in terms of performance, only polymer lithium-ion batteries can meet this demand
