The current plant protection drone is mostly used as a source of power, and the battery is also an important part of the plant protection drone system. Its price is worthy, correct use and maintenance can make it more durable  But  The discharge curve of the battery indicates that the voltage drop is faster when the discharge is started, but the discharge is between 3.

9 to 3.7V, and the voltage drop is not fast. But once it is reduced to 3.

7V, the speed of the voltage will speed up, the control is not good, resulting in overhanging, slightly damaged the battery, and the mass is too low. Some flying friends are less than the battery, so they will float each time. This battery is very short.

The strategy is, try to fly less than one minute, and fly a loop in life. Ning Cai battery is purchased two, do not fly the battery over the capacity limit each time. To make full use of a battery alarm, alarm should land as soon as possible.

  Filling  This is required for the charger. Some chargers are not perfect. It has caused the single-chip battery full of 4.

2V and has not stopped charging. In addition, some charger uses a period of time because the components are aging, it is easy There is a problem that is full, so, when the lithium-based battery is charged, it must be seen. When the charging time is too long, it is necessary to manually check whether the charger has failed.

If there is a failure, you should unplug the battery as soon as possible, otherwise the lithium poly battery If you charge, you will drive the battery life. Also reminded, when charging, it must be charged according to the number of charged cates specified in the battery, and cannot exceed the specified charging current  Not filled with electricity  Full electric battery, can not be filled for more than 3 days, if you don't turn off more than a week, some batteries can drum directly, some batteries may not be temporary drums, but after a few times, the battery may be scrapped directly.

Therefore, the correct way is that after receiving the flight task, it is recharged, and if there is no flight task within 3 days, please save the single chip voltage to 3.80 ~ 3.90V.

If there is a mixed electricity, it is not flying due to various reasons, but also to discharge the battery to 3.80 ~ 3.90V saved within 3 days.

If the battery is not used within three months, the battery is charged and placed once, so that the battery life can be extended. Battery preservation should be placed in a cool environment, when the battery is stored for a long time, it is best to be placed in a sealed bag or sealed in the release box, it is recommended to have a ambient temperature of 10 to 25c, dry, non-corrosive gas  Do not damage the outer skin  The outer skin of the battery is an important structure that prevents battery explosion and leakage.

The aluminum-plastic outer skin of lithium-poly battery will directly lead to fire or explosion. The battery should be handled lightly, when the battery is fixed on the plane, the tight is tight. Because it is possible to do a big dynamic flight or cutting machine, the battery will take out because it is tight, which is easy to cause the outer skin damage.

  Short circuit  This situation often occurs during battery welding wire maintenance and transportation. The short circuit will directly cause the battery to fire or fire explosion. When it is found that the battery has a broken line after a period of time, it is necessary to pay attention to the electric soldering iron to contact the positive and negative electrode of the battery.

In addition, during the process of transporting the battery, the best way is that no battery is separately set on a self-sealing bag and placed in the explosion-proof box, preventing the positive and negative electrodes of a piece of battery due to bumps and collisions due to bumps and collisions. Other conductive materials are shorted or short-circuited. See Figure 4, that is, battery short circuit leads to scrap.

  Safe placement environment  1, do not charge and discharge high / low temperature environment. Extreme temperatures affect the performance and life of the battery, check whether the used batteries have been cooled before charging, do not charge and discharge near cold garage, basement, sunlight or heat source  2, battery storage should be placed in a cool environment.

When the battery is stored for a long time, it is best to be placed in a sealing bag or a sealed explosion-proof box, which is recommended to have a ambient temperature of 10 to 25c, dry, non-corrosive gas  3. Before take-off, it is necessary to keep the battery to keep the battery in a warm environment, such as in the house, in the car, insulation box.

Quickly install the battery when you take off and perform a flight task. Try to shorten the time to half the normal temperature state when flying at low temperature is guaranteed. There is often low temperature weather in the north or high altitude area.

At this time, the battery is placed in the outside, and its discharge performance will be greatly reduced. If it is also flying in the flight time in normal temperature, it will definitely. The alarm voltage should be raised (such as a single-chip alarm voltage to 3.

8V), as the pressure drop in a low temperature environment will be very fast, the alarm is immediately landed  Safe transportation  The battery is most afraid of bumps and friction, transport bumpers may cause short circuit of the battery outside, short circuits directly cause the battery to fire or fire explosion. At the same time, it is necessary to prevent the conductive material from simultaneously contacting the positive and negative electrode of the battery.

During transportation, the best way is to give the battery separately after the bag is placed in the explosion-proof case. Some pesticide auxiliaries are a flammable aid, so the pesticide should be separately placed  Stay away from pesticides to prevent battery corrosion  The potion in the operation has a certain corrosive battery, and the external protective is not in place.

Incorrect usage is also possible to corrode the battery's plug. Therefore, the user must prevent the corrosion of the battery when the user is actually actually charged. The battery must be kept away from the drug when the battery is placed, so that the drug to the battery can be reduced.

  Correct storage battery  The battery subject, handle, wire, power plug should be checked, and observe whether the appearance is damaged, deformed, corrosive, discolored, broken, and whether the plug and the plane of the plane are too loose. Each job is over, you must use a dry cloth to wipe the battery surface and power plug to ensure that there is no pesticide residue to avoid corrosion batteries. After the end of the flight, the battery temperature is high, and the temperature of the flight battery is required to drop below 40 ° C and then charge it (the optimum temperature of the flight battery is 5 ° C to 40 ° C).

After the job is over, it is recommended to slow charging the battery  ★ Summer: Removing the battery from the outdoor high temperature discharge or at high temperatures, it is best not to charge immediately. After the surface temperature of the battery is lowered, it can be charged, which greatly increases the life cycle of the battery.

The temperature in summer is relatively high, the battery is preferably not exposed in the sun  ★ Winter: After discharge, the battery takes effective insulation measures (such as the use of an incubator) to ensure that the temperature of the battery is maintained above 5 ° C, and the battery life will have significant shortening in low temperature environment, and there is a low power quantity alarm. Return immediately.

  Emergency disposal  When the battery starts on the charging station, first cut off the device power supply; use the asbestos glove or the hool tongs to pick up the lithium-ion battery on the charging station, sequentially in the ground or fire sandrel. The flames of lithium-ion batteries on the ground were covered with asbolt blankets. The fire sand is covered with the stone blanket.

If you need to use the exhaustible battery, apply brine to completely soak the battery for more than 72 hours, and ensure that it is completely discharged  ★ Do not extinguish with dry powder, due to dry powder, the solid metal chemical fire is covered with a large amount of dust, and the equipment is corroded, polluted space  ★ Carbon dioxide does not pollute the space and corrosion machine, but can only achieve the instantaneous suppression use of the flame, need to be used with sand, asbestos blanket.
