Mastering the use of drone batteries in a hot environment makes work safer
Many areas experienced temperatures above 36 degrees Celsius. Such a temperature and working environment is a huge test for drone work. As an important part of the drone power system, the battery is expensive, and in the scorching sun and high temperature, special attention should be paid to maintenance and use to make it more durable，，Let’s talk about the use and maintenance precautions of drone batteries in hot weather
We need to understand the materials of drone batteries. In recent years, more and more UAV batteries use lithium polymer batteries, compared with ordinary batteries, lithium polymer batteries have the advantages of high rate, high energy ratio, high performance, high safety, long life, environmental protection and pollution-free, and light weight. In terms of shape, lithium polymer batteries have ultra-thin characteristics, which can be made into batteries of different shapes and capacities according to the needs of some products.
Precautions for daily use of drone operations
First of all, the use and maintenance of the drone battery should regularly check the battery body, handle, wire, power plug, to observe whether the appearance is damaged, deformed, corroded, discolored, broken skin, and whether the plug and the aircraft are too loose.
After the flight, the battery temperature is high, we need to wait for the temperature of the battery to drop below 40°C before charging it (the optimal temperature range for charging the flight battery is 5°C to 40°C).
Remember: Do not use bulging batteries easily (especially in hot weather environments)
In the summer of high temperature, it is best not to charge the battery immediately after discharging from outdoor high temperature or at high temperature, and charge it after the surface temperature of the battery drops. Summer is the high season for drone battery accidents, especially when going out, due to the increase in the temperature of the surrounding environment, coupled with high-intensity use, it is easy to cause the battery temperature to be too high. Too high battery temperature will cause instability of the internal chemicals of the battery, light will greatly shorten the battery life, and more serious may cause the drone to explode, and even cause a fire! This requires special attention to the following points:
- When working in the field, the battery must be placed in a cool place to avoid direct sunlight
- When the battery heating up is serious, please reduce it to room temperature and recharge
- Pay attention to the battery status, once you find that the battery is bulging, leaking and other phenomena, you must stop using it immediately
- When using the battery, pay attention to handle it gently, do not bump the battery
- Grasp the operation time of the drone, and the voltage of each battery during operation should not be lower than 3.6V
Drone battery charging precautions
Charging is the process of high incidence of battery accidents, especially in summer, the outdoor temperature height is more than thirty degrees, we often see battery cars, electric vehicles charging led to battery fire safety accident news, the same reason, drone battery summer high temperature charging should also pay special attention, charging must be supervised. If there is a failure, the battery needs to be unplugged as soon as possible, the battery is overcharged, the battery life may be affected at light, and an explosion may occur at worst.
- The battery charger must use a regular brand that is compatible with the battery (preferably from the manufacturer)
- Do not overcharge the battery to avoid damage to the battery or danger. Try to choose chargers and batteries with overcharge protection, such as the series of drone batteries and charger series launched by Zhengfang Technology, which have overcharge protection functions
Drone battery transportation precautions
Drones often operate in the field, so the safety of battery transportation has become an unavoidable issue. When transporting the battery, it is necessary to pay attention to avoid the collision of the battery, the collision of the battery may cause a short circuit of the external equalizer line of the battery, and the short circuit will directly lead to battery damage or fire and explosion. At the same time, it is also necessary to avoid short circuits caused by conductive substances contacting the positive and negative electrodes of the battery at the same time.
During transportation, the best way is to put the battery in a separate ziplock bag and place it in an explosion-proof box and place it in a cool place.
- Ensure the safety of the battery during transportation, do not collide, squeeze the battery
- Batteries need to be transported in a special safety box
- Place buffer foam between the batteries, pay attention to not be closely arranged, to ensure that the batteries cannot squeeze each other
- The plug should be connected to the protective cover to avoid short circuit
