In the use of the battery, you should stick to six not, the correct way to use is the best way to extend battery life. 1, but the charger is required, some chargers are not perfect after the oil distribution function, resulting in a single-chip battery that has not stopped charging in 4.2V, and some charger uses a period of time because components Aging, it is also easy to have a problem that the problem is not stopped.

Therefore, it must be seen when the lithium-cylorch is charged. When the charging time is too long, it is necessary to manually check the charger. If there is a failure, it is necessary to unplug the battery as soon as possible.

Otherwise, if the lithium poly battery is overcharged, it will affect the battery life, and the stroke is suddenly exploded. Also reminded, it must be charged according to the number of charging C, or lower in the battery specified in the battery, and cannot exceed the specified charging current. 2, but the discharge curve of the discharge battery is declared, when the discharge is started, the voltage drop is faster, but the discharge is between 3.

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

7V, the speed of the voltage will speed up, the control is not good, resulting in over-delivery, light damage, the battery, the voltage is too low, the oil. Some models have fewer batteries, so they will float each time. This battery is very short.

The strategy is, try to fly less, fly a cycle with a life life. Ning Cai battery is more, do not fly the battery to exceed the capacity limit each time. It is necessary to use the battery alarm, and alarm should land as soon as possible.

3, dissatisfied to save the overflowable battery, can not be filled for more than 3 days, if you don't turn it off, some batteries are straight, some batteries may not be temporary drums, but after a few times, after storage, the battery Maybe a pen. 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, the battery is discharged to 3.80 ~ 3.

90V in 3 days after all the fuse. If the battery is not used in three months, the battery is charged and discharged, so that the battery life can be extended. Battery storage should be placed in a cool environment.

When the battery is stored for a long time, it is best to place in the sealed bag or sealed in the burst, the ambient temperature is 10 ~ 25°C, dry, non-corrosive gas 4, the outer skin of the outer skin battery is a critical structure of alert battery explosion and leakage, and the aluminum-plastic outer skin of the lithium-poly battery will lead to the battery to start or explode. The battery should be lightly put, when the battery is fixed on the plane, the strap should be tight. Because it is possible to do a big dynamic flight or cutting machine, the battery will take out because it is tipped, which is easy to cause battery skin damage.

5, this situation is not shorted often occurs during maintenance and transportation of battery welding lines. Short circuit leads leads to battery 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 special attention to the electric soldering iron not 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 separate bag and placed in an explosion-proof box, and the alert is due to the bump and collision due to bumps and collisions at the same time. Other conductive materials short or broken. 6, don't cool this principle, many flying friends will ignore.

There is often low temperature weather in the north or high altitude. At this time, the battery is placed in the outside. Its discharge performance will be greatly reduced.

If it is necessary to fly during the flight time, then there must be a problem. At this point, the alarm voltage should be raised (such as a single-chip alarm voltage to 3.8V), because the pressure drop in the low temperature environment will be very fast, the alarm will immediately land immediately.

If you want to keep the battery, you should save the battery in a warm environment before takeoff, such as in the house, in the car, insulation box, etc. Quickly install the battery when you take off, and perform a flight task. Try to shorten the time to half of the normal temperature status while flying at low temperature to ensure safe flight.
