What can be done to prolong the service life of lithium battery of UAV?

　　The discharge curves of lithium-ion batteries show that the voltage drops rapidly at the beginning of the discharge, but the voltage drop is stable between 3.9 and 3.7V. However, once the voltage drops to 3.7V, the voltage drop accelerates. If not properly controlled, this can lead to excessive discharge, which can at least damage the battery, or cause an accident if the voltage is too low. If you do not pay attention to the protection of the battery, often excessive discharge, battery life will be greatly shortened. The drone, for example, can monitor battery usage in real time from flightgoapp. By default, a low battery power alarm is triggered when the remaining battery power is lower than 30%. When the remaining battery power is too low, flightgoapp will raise a severe low battery alarm, and the plane will automatically enter and land at the return point to ensure battery performance and flight safety

　　1. Use special charger

　　2. Battery outer packaging is an important structure to prevent battery explosion, liquid leakage and fire. Be careful when handling batteries

　　3, the battery should not be fully charged and stored for a long time, otherwise the battery may expand during use

　　4. Batteries should be stored in a cool environment. When storing batteries for a long time, it is best to put them in a sealed bag or sealed explosion-proof box. The recommended environment temperature ranges from 10 ° C to 25 ° C, and is dry and free of corrosive gases

　　5. When installing the battery on the UAV, ensure that the battery cover is fastened to prevent the battery cover from loosening and falling off during the flight, resulting in damage to the battery case and accidents. Short circuit will directly lead to battery ignition or fire explosion

　　6. In the process of battery transportation, the battery should be prevented from being put together with metal objects such as keys. The best way to do this is to place each battery in a separate self-sealing bag and place it in a flameproof case to prevent short circuits caused by collisions and collisions during transport

　　7. Recharge the battery after the mission is confirmed. If there is no flight mission within 3 days after the battery is used, please discharge and save. If the take battery is not used within two months, the battery should be charged and discharged once before continuing to be stored to keep the battery active and extend its service life

　　8, do not use at 0C temperature, otherwise it may cause irreversible damage to the battery. Quickly install batteries and fly missions before takeoff. Shorten the flight time. When the ambient temperature is low, the service time of batteries may be shortened dramatically. Try to shorten the flight time to half the normal temperature to ensure flight safety. Cold weather often occurs in the north or at high altitudes. If the battery is kept in low temperature for a long time, the discharge performance will be greatly reduced. At this time, it cannot be controlled according to the flight requirements at room temperature. Battery insulation treatment Before takeoff, the battery should be kept in a warm environment, such as indoors, inside the car, incubator, etc. Please preheat the battery to above 5C before installing it on the plane. It's best to preheat it to over 20 degrees Celsius. Keep rechargeable batteries and chargers in a safe place. The Take charger uses Qualcomm QC3.0 fast charging technology and can be used in conjunction with a supported power adapter for fast charging. QC3.0 In the fast charging state, the charging status indicator blinks green. If you do not use the matched power adapter, the fast charging effect may not be achieved. You can only charge slowly. In the slow charging state, the charging status indicator is orange and blinking.
