There are many types of batteries. The characteristics of batteries are like people's personalities. Everyone has different personalities, and batteries also have their own properties. Here I will explain to you the advantages and disadvantages of several common types of drone batteries.
When it comes to the characteristics of batteries, we have to popularize several measurement standards. One is the energy density of the battery. It can be simply understood that a battery with a large energy density has a longer battery life than a battery with a small energy density. The second is the discharge multiple. The larger the discharge multiple, the greater the current that the battery can discharge. Usually, the charging current of a battery with a large discharge multiple can also be larger. The third is the battery voltage. Under the same power, the higher the voltage, the smaller the current required.
Polymer lithium battery, a common drone battery, is also used by most remote controllers. Its advantages are obvious to all, with high voltage and large discharge multiples. The output power is one of the best among batteries. Take the battery in the picture for example, it weighs 190 grams but can output more than 1800 watts. The energy density is also relatively large, the manufacturing process of polymer lithium batteries is relatively mature, and the cost performance of the battery is relatively high. The disadvantage is that polymer lithium batteries are very active and not very stable. Here, it specifically refers to the risk of fire and explosion when it is hit hard and short-circuited, which is much higher than other batteries.
Lithium iron phosphate battery, commonly used in electric packs, has the advantages of cost-effectiveness and stability. It has a high cost-effectiveness among several batteries, and its stability is also very high. At the same time, it has its unique personality. Over-discharge does less damage to the battery, and it can usually be discharged to 2 volts (but overcharging will damage the battery and it is easy to scrap it). In addition to its advantages, the rest are all its disadvantages, such as low voltage, full voltage is only 3.65 volts, and the discharge multiple is not large (the charging current is also relatively small).
18650 battery, as the name implies, is a cylindrical battery with a diameter of 18 mm and a height of 65 mm. The battery used by drones that pursue long-range flight is usually used on long-range fixed-wing aircraft, and can also be used in power packs. Its advantages are also obvious, with high energy density and higher stability. It is also very convenient to assemble the battery yourself, just like stacking the batteries like building blocks, but you need a spot welder (not very expensive, in fact, you can also DIY with a spot welder). Let's talk about the disadvantages of the battery (compared to polymer lithium batteries) The battery discharge capacity is low (the discharge capacity of Sony c6 can reach 30A). The battery voltage is low, although the full voltage is also 4.2 volts, but the voltage drops very quickly.
Each battery has its own advantages and disadvantages, but each battery is used in every aspect of our lives. Drone batteries are now a hot battery type and have also attracted a lot of attention. Jinchi Technology strictly requires standards when making batteries and has also received support from many people in the industry.
