Pay attention to the following points in the use of the drone battery . The correct method of use is the best way to extend battery life.
One: but put
The discharge curve of the battery shows that the voltage drops faster when the discharge starts, but the discharge drops to 3.9~3.7V, and the voltage drops not fast. However, once it drops to 3.7V, the voltage drop speed will increase. If the control is not good, it will lead to over-discharge. If it is light, it will damage the battery, but the voltage will be too low to cause the bomber. Some model friends have a battery because they have fewer batteries, so the battery is short-lived. The strategy is to fly as little as one minute and the life span is one more cycle. Would rather buy two more batteries, and don't fly the battery beyond the capacity limit every time. To make full use of the battery alarm, an alarm should land as soon as possible.
Two: not charge
This has requirements for the charger. Some chargers have a power-off function that is not perfect after being fully charged. As a result, the single-chip battery is fully charged to 4.2V and has not stopped charging. In addition, some chargers are used for a period of time, because the components are aging, and easy. There is a problem that the battery is full and does not stop. Therefore, when the lithium battery is charged, it must be taken care of. When it is found that the charging time is too long, it is necessary to manually check whether the charger is faulty. If there is a fault, unplug the battery as soon as possible, otherwise the lithium battery If it is overcharged, it will affect the battery life, but it will directly explode and catch fire. Also remind everyone that when charging, be sure to charge according to the battery charge C number or lower C number, not exceed the specified charging current.
Three: not full of electricity to save
A fully charged battery cannot be fully charged for more than 3 days. If it is not discharged for more than one week, some batteries will be directly bulged. Some batteries may not be drummed for a while, but after several times of full power storage, the battery may be directly scrapped. Therefore, the correct way is to recharge after receiving the mission. If the battery does not have a mission within 3 days after use, please charge the monolithic voltage to 3.80~3.90V. After charging, there is no flight for various reasons. It is also necessary to discharge the battery to 3.80~3.90V within 3 days after filling. If you do not use the battery within three months, continue to save the battery after charging and discharging it once, which will extend battery life. The battery should be stored in a cool environment. When storing the battery for a long time, it is best to put it in a sealed bag or a sealed blasting box. The recommended ambient temperature is 10~25°C, and it is dry and non-corrosive.
Four: no damage to the skin
The outer skin of the battery is an important structure to prevent battery explosion and liquid leakage. The damage of the aluminum plastic outer skin of the lithium poly battery will directly cause the battery to catch fire or explode. The battery should be handled with care. When the battery is fixed on the aircraft, the cable tie should be tightened. Because it is possible to make a large dynamic flight or a crash, the battery will be pulled out because the cable tie is not tight, which is also likely to cause damage to the battery skin.
Five: no short circuit
This often happens during battery wire maintenance and transportation. A short circuit can directly cause the battery to ignite or explode. When it is found that the battery has been disconnected after a period of use, it is necessary to re-solder the wire. Pay special attention to the soldering iron not to touch the positive and negative terminals of the battery at the same time. In addition, in the process of transporting the battery, the best way is to not have a battery separately put on the ziplock bag and placed in the explosion-proof box to prevent the positive and negative poles of a certain battery from being encountered at the same time due to bumps and collisions during transportation. Other conductive materials are short-circuited or broken and short-circuited. See Figure 4, which is a battery short circuit that leads to scrap.
Six: don't catch cold
This principle, many flying friends will ignore. In the north or high altitude areas, there will often be low temperature weather. When the battery is placed outside for a long time, its discharge performance will be greatly reduced. If it is to fly at the time of normal temperature, it will definitely cause problems. At this point, the alarm voltage should be raised (for example, the single-chip alarm voltage is adjusted to 3.8V), because the voltage drop will be very fast in the low temperature environment, and the alarm will immediately fall. In addition, the battery should be insulated. Before the take-off, the battery should be stored in a warm environment, such as inside a house, inside a car, or in an incubator. Quickly install the battery when taking off and perform the mission. Try to shorten the time to half of the normal temperature when flying at low temperatures to ensure safe flight.
