The drone power battery is made up of 4 batteries in series, and the voltage of the single battery is 4.35V after being filled.
In daily use, the chip inside the smart battery can ensure that the voltage difference between each piece is less than 0.2V, but when the battery is over-discharged (single-chip voltage <3V), the voltage difference between the cells may be greater than 0.2V. At this time, the battery will be permanently damaged: the battery capacity will be seriously reduced. Generally speaking, it is so much power before it can be put in, which will seriously shorten the battery life.
In addition, when the voltage of a certain battery cell drops below 3v, the battery power will be directly displayed as 0 because the battery cell has been seriously over-discharged. When this happens, the drone can still barely fly, so please Keep calm and drop the drone to a safe place.
And even if the charging causes the voltage and voltage difference to return to normal levels, the battery has been permanently damaged.
View the status information of the battery:
After connecting the drone, you can view it in app-Setup - Battery Info. The voltage of the cells 1, 2, 3, 4 is the voltage of a single cell. If you find that the battery information is abnormal, please stop using the battery and contact the after-sales service as soon as possible. So as not to cause greater losses.
How to avoid battery over-discharge:
When the aircraft is in the air, for safety reasons, even if the over-the-counter drone will continue to fly, when the drone is in the 30% low-power alarm, it should land as soon as possible, instead of forcibly pulling high, no Man-machine mobility is also limited by software, preventing excessive maneuvering and causing a rapid drop in battery power.
Serious over-discharge can cause damage to the battery. And because the smart battery itself consumes a part of the power, the battery should be fully charged before the long time is used. The smart battery chip will automatically adjust the internal voltage of the battery to the storage voltage after 12 hours (about 75%).
Battery overheat protection and charging:
The energy density in lithium battery is high, so the control of battery temperature is especially important. When you have just finished flying, the battery temperature is high. Please put it in between and then charge it. Of course. The chip inside the smart battery also has a protection function, and when it is higher than 40 °C, it will automatically stop charging. Therefore, when you find that the battery that has just finished flying does not charge, you can wait for a while, and wait for the battery temperature to drop, you can charge normally.
The smart battery has no charging memory and can be charged at any time. When the battery is full, the charger can be unplugged. Otherwise the battery will remain at a high voltage for a long time, affecting battery life. Please try to use it as much as possible. You can charge the battery to about 75% and then fully charge the battery before use.
Use under low temperature conditions:
Lithium batteries are sensitive to low temperature, which is determined by the characteristics of lithium batteries. When the temperature is too low, the discharge capacity of the battery becomes weak, and the remaining capacity of the battery will fluctuate greatly. This will cause a large flight to the drone. The impact, how to make the battery work normally, is the focus of low-temperature flight.
1: In cold weather, the battery should be preheated to about 25 degrees to keep the battery working normally when the flight starts. After the drone starts working, the battery will continue to discharge. At this time, the battery discharge process will also occur. The heat ensures that the drone can fly normally.
2: During the winter flight, always pay attention to the change of power, reduce the flight time to half of the normal time, and avoid the drone's inability to return to the air or other unexpected situations due to the sudden drop of low temperature power.
3: When used in peacetime, you can check the battery data through the millet drone APP-set-battery information, and control the battery status in real time to ensure our flight status.
4: Low-power alarms fall in time to avoid unnecessary loss of battery over-discharge.
5: Flying in cold weather, the human body is easy to reflect dull due to low temperature, especially the cold of the hand will affect the operation feel of the drone. If you go out to fly, you must pay attention to your own warmth.
Smart battery life:
Before we understand the battery life, we should first understand the number of cycles of the battery. The battery counts 80% per discharge, assuming that the total power is 5000, and each 4000 is a cycle.
If you put 1000 each time, the cycle is counted 4 times. The life of a smart battery is 200 cycles. After 200 cycles, the battery capacity will decrease drastically. Please replace the battery as soon as possible.
