1. No filling
There are requirements for chargers. Some chargers do not have perfect power-off function after they are fully charged. Therefore, when lithium-polymer batteries are charged, someone must take care of them. When it is found that the charging time is too long, it is necessary to check whether the chargers are faulty manually. If there is a fault, unplug the batteries as soon as possible. Otherwise, if the lithium-polymer batteries are overcharged, the battery life will be affected, and the battery life will be directly affected The explosion caught fire. In addition, we remind you that when charging, you must charge according to the specified charging C number or lower C number of the battery, and do not exceed the specified charging current.
2. Don't let it go
The discharge curve of the battery shows that the voltage drop is relatively fast at the beginning of discharge, but the voltage drop is not fast when the discharge reaches 3.9 ~ 3.7V. However, once the voltage drops to 3.7V, the speed of voltage drop will be accelerated. If the control is not good, it will lead to over discharge. If the control is not good, it will damage the lithium battery of UAV, and if the voltage is too low, it will cause explosion. Some model friends because of less batteries, so every time they fly over, such a battery is very short-lived. The strategy is to fly as little as possible for one minute and one more cycle for life. It's better to buy two more lithium batteries than to fly them over the capacity limit every time. To make full use of the battery alarm, the alarm should be lowered as soon as possible.
3. Storage of insufficient electricity
The fully charged lithium battery cannot be stored for more than 3 days at full charge. If it is not released for more than a week, some batteries will be directly packed. Some batteries may not be able to drum temporarily, but after several times of full charge storage, the batteries may be directly discarded. Therefore, the correct way is to recharge the battery after receiving the flight mission. If there is no flight mission within 3 days after using the battery, please charge the single-chip voltage to 3.80 ~ 3.90v for storage. In addition, if the battery fails to fly due to various reasons after charging, discharge the battery to 3.80-3.90v within 3 days after charging. If the battery is not used within three months, the battery shall be charged and discharged once and kept continuously, so as to prolong the battery life. The battery shall be stored in a cool and shady environment. When the battery is stored for a long time, it is better to put it in a sealed bag or a sealed explosion box. The recommended ambient temperature is 10 ~ 25 & deg; C, and it is dry and free of corrosive gas.
