For the maintenance of plant protection drones, we can't just maintain the equipment of plant protection drones, we should also maintain the batteries of plant protection drones, because only by using the batteries correctly can the battery life be extended, and at the same time It can also prolong the service life of the plant protection drone, so how should we properly maintain the battery of the plant protection drone? Let the editor of ManHope give you a detailed introduction. The specific method is as follows:
1. battery Not over discharge
The battery voltage drops too fast, and if the control is not good, it will lead to over-discharge, which will damage the battery at the slightest, and cause the bombing if the voltage is too low. Some pilots will over-discharge every time they fly because they have less batteries. Such batteries are very short-lived.
The strategy is, try to fly for one minute less, and fly one more cycle of life. It is better to buy two more batteries than to fly the battery beyond the capacity limit every time. Therefore, all pilots should use the battery strictly according to the flight requirements. When the low battery alarm of the aircraft, it should land as soon as possible.
2. After the battery is fully charged, it cannot continue to charge
Some chargers have imperfect power-off function after being fully charged, causing the single-chip battery to be fully charged to 4.2V without stopping charging. In addition, after some chargers have been used for a period of time, due to the aging of components, it is also prone to the problem of non-stop charging. However, if the lithium battery is overcharged, it will affect the life of the battery in the slightest, and it will explode and catch fire in the severe case. Therefore, to prevent lithium batteries from being overcharged, the following points should be noted:
a. Use the original factory dedicated charger. ManHope's special charger for plant protection drones has charging and maintenance functions, and has multiple charging protections such as overvoltage, overcharge, and overcurrent. It is easy to operate, integrated design, and easy to transition.
b. Accurately set the number of battery cells in the battery pack. You have to watch the charger's display carefully for the first few minutes of charging, where it will show the number of cells in the pack. If you don't know, you should not charge or use a charger you are familiar with.
c. Charge a new lithium battery pack for the first time, check the voltage of each battery cell in the battery pack, and do the same work every 10 times of charging and discharging. Doing so is absolutely necessary, a battery pack with unbalanced voltages will still burst when the number of cells is correctly charged. If the voltage difference of the battery cells in the battery pack exceeds 0.03 volts, it can be recharged with a small current to make up for the voltage difference). If the voltage difference of the battery cells exceeds 0.1 volts after each discharge, it means that your battery has been damaged and should be used carefully or replaced in time.
d. Do not charge if left unattended. When charging, it must be charged according to the charging C number specified by the battery or a lower C number, and the specified charging current must not be exceeded.
3. Save when the battery is not fully charged
The chemical properties of a fully charged battery are extremely active, and cannot be stored for more than 3 days. If it is not released for more than a week, there is a risk of flatulence. Some batteries may not bulge temporarily, but after several times of fully charged storage, the battery may directly scrapped.
Therefore, users should charge the plant protection drone before use. If the aircraft does not take off after being charged, the battery should be discharged to the stored capacity within 3 days after being fully charged. If the battery has not been used within three months, the battery should be charged and discharged once before storage, which can prolong the battery life.
4. Safe battery placement
a. Handle with care. The outer skin of the battery is an important structure to prevent the battery from exploding and leaking, and damage to the outer skin of the battery will directly cause the battery to catch fire or explode. The battery should be handled with care, and the cable tie should be tightened when fixing the battery on the plane. Because it is possible that during a large dynamic flight or crash, the battery will be thrown out because the cable tie is not tight, which will easily cause damage to the battery skin.
b. Do not charge and discharge in high/low temperature environment. Extreme 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.
c. Batteries 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 explosion-proof box. The recommended ambient temperature is 10~25°C, and it is dry and free of corrosive gases.
5. Safe transportation of batteries
Batteries are most afraid of bumps and frictions. Bumps during transportation may cause a short circuit in the external balance line of the battery, which will directly cause the battery to catch fire or explode. At the same time, it is necessary to avoid the short circuit caused by the conductive material contacting the positive and negative electrodes of the battery at the same time.
