How to use the customized lithium battery for plant protection machine correctly?
1. Customized lithium battery for plant protection machineBattery is not discharged
Customized lithium battery for plant protection machineBattery voltage drops too fast, and poor control will lead to over-discharge, which will damage the battery at the least, and cause the machine to explode if the voltage is too low. Some pilots have fewer batteries, so they over-discharge them every time they fly, and such batteries have a short life. Little do they know that this actually greatly increases the cost of use.
The corresponding strategy is to fly as little as possible for one minute, and the life span will be increased by one more cycle. It is better to buy two more batteries than to exceed the capacity limit every time. Therefore, pilots should use batteries strictly according to flight requirements. When the low battery alarm sounds, the aircraft should land as soon as possible.
2. Customized lithium battery for plant protection machineBattery not overcharged
Some chargers have an imperfect power-off function after being fully charged, resulting in the single-chip battery not stopping charging even when it is fully charged to 4.2V. In addition, some chargers are prone to the problem of not stopping charging after being fully charged due to aging of components after being used for a period of time. If the lithium battery is overcharged, it will affect the battery life at the least, and even cause explosion and fire. Therefore, to prevent customized lithium batteries for plant protection machines from overcharging, the following points should be noted:
1. Use a dedicated charger. This charger can be a lithium-ion or lithium-polymer charger, which are very similar. Some mobile phone chargers can be used to charge lithium-polymer batteries, which will not damage the battery.
2. Accurately set the number of battery cells in the battery pack. In the first few minutes of charging, you need to carefully observe the charger's display screen, which will show the number of batteries in the battery pack. If you don't know, you should not charge or use a charger you are familiar with.
3. Charge a brand new lithium battery pack for the first time and check the voltage of each battery cell in the battery pack. The same work should be done every 10 charges and discharges thereafter. This is necessary. A battery pack with unbalanced voltage will still burst when the number of batteries is selected correctly for charging. If the voltage difference of the battery cells in the battery pack exceeds 0.1 volt, the voltage of each battery should be charged to 4.2 volts to make them equal. If the voltage difference of the battery cells exceeds 0.1 volt after each discharge, it means that the battery has failed and should be replaced in time.
4. Do not charge without supervision. When charging, be sure to charge according to the charging C number specified by the battery or a lower C number, and do not exceed the specified charging current. The charged battery and charger must be placed in a stable position.
Three, Plant protection machine customized lithium batteryUnfull power storage
1. Customized lithium battery for plant protection machineThe chemical properties of fully charged batteries are very active, so they cannot be stored for more than 3 days. If they are not discharged for more than a week, there is a risk of bloating. Some batteries may not swell temporarily, but after several full-charge storages, the batteries may be directly scrapped.
2. The correct charging method should be to charge the plant protection drone before the flight mission. If there is no flight mission within 3 days after the battery is charged, please charge the single chip voltage to 3.80~3.90V for storage. If the battery has not been used within three months, charge and discharge the battery once and continue to store it, which can extend the battery life.
3. The battery should be stored in a cool environment. When storing the battery for a long time, place it in a sealed bag or a sealed explosion-proof box. The recommended ambient temperature is 10~25°C, and it should be dry and free of corrosive gases.
Fourth, Customized lithium battery for plant protection machineDo not damage the packaging
Customized lithium battery for plant protection machineThe outer packaging of the battery is an important structure to prevent battery explosion and leakage fire. The damage of the aluminum plastic film of the lithium polymer battery will directly cause the battery to catch fire or explode. The battery should be handled with care. When fixing the battery on the aircraft, the cable tie should be tightened. Because it is possible that the battery will be thrown out due to loose cable ties during large dynamic flight or crashing, which can easily cause damage to the battery skin.
V. Prevent short circuit during transportation
1. Batteries are afraid of bumps and frictions. Bumps during transportation may cause short circuits in the external equalization line of the battery, which can directly lead to ignition or explosion of the battery.
2. Avoid short circuits caused by conductive materials contacting the positive and negative electrodes of the battery at the same time.
3. During the transportation of batteries, the solution is to put the batteries in a ziplock bag and place them in an explosion-proof box to prevent the positive and negative electrodes of a battery from touching other conductive materials at the same time and causing a short circuit due to bumps and collisions during transportation. Since some pesticide adjuvants are flammable adjuvants, pesticides should be placed separately from batteries.
VI. Placement Environment
1. Do not charge or discharge in high or low temperature environments. Temperature will affect the performance and life of the battery. Before charging, check whether the used battery has cooled down. Do not charge or discharge in a cold garage, basement, under direct sunlight or near a heat source.
2. The battery should be stored in a cool environment. When storing batteries for a long time, place them in a sealed bag or a sealed explosion-proof box. The recommended ambient temperature is 10~25°C and the environment is dry and free of corrosive gases.
3. Customized lithium battery for plant protection machine Before takeoff, the battery should be insulated and Customized lithium batteries for plant protection machines should be stored in a warm environment, such as in a house, car, or in an incubator. Install the battery quickly when taking off and perform the flight mission. When flying at low temperatures, try to shorten the flight time to half of that at normal temperatures to ensure flight.
