How to use and maintain the UAV lithium battery?

How to use and maintain the lithium battery of the drone 1. However, there are requirements for charging the charger. Some chargers have imperfect power-off function after being fully charged. Therefore, someone must take care of the lithium polymer battery when charging is found. When the time is too long, manually check whether the charger is malfunctioning. If there is a malfunction, unplug the battery as soon as possible. Otherwise, if the lithium polymer battery is overcharged, it will affect the battery life in the slightest, and it will directly explode and catch fire. In addition, remind everyone that when charging, be sure to charge the battery according to the specified charging C number or a lower C number, and not exceed the specified charging current. 2. However, the discharge curve of the discharged battery shows that the voltage drops relatively fast at the beginning of the discharge, but when the discharge reaches between 3.9V and 3.7V, the voltage drops not fast. But once it drops to 3.7V, the voltage drop speed will increase. Poor control will lead to over-discharge, which will damage the UAV's lithium battery, or cause a bomber if the voltage is too low. Some model friends will over-discharge every time they fly because they have fewer batteries. Such batteries are very short-lived. The strategy is to fly one minute as little as possible, and one more cycle of life. It is better to buy two more lithium batteries than to fly the battery to exceed the capacity limit each time. To make full use of the battery alarm, you should land as soon as possible. 3. If the battery is not fully charged, the fully charged lithium battery cannot be stored for more than 3 days. If it is not discharged for more than a week, some batteries will be swollen, and some batteries may not swell temporarily, but after a few times of fully charged storage, The battery may be directly scrapped. Therefore, the correct way is to charge it after receiving the flight mission. If there is no flight mission within 3 days after the battery is used, please charge the voltage of the single chip to 3.80~3.90V and save it. If the battery does not fly due to various reasons after it is fully charged, the battery should be discharged to 3.80~3.90V and stored within 3 days after being fully charged. If the battery is not used within three months, continue to store the battery after charging and discharging it once to extend the battery life. The battery should be stored in a cool environment. When storing the battery for a long time, it is best to put it in a sealed bag or a sealed explosion box. The recommended ambient temperature is 10~25C, and it is dry and non-corrosive.
