Haha, first of all, let me explain: 1. The one with a T head, that is, the one with only two red and black wires, is the terminal where the lithium battery is connected to the motor of the model or recipient. 2. This set of four wires, with red, green, yellow and black plugs, is a dedicated charging port and connection port for the lithium battery to connect to a dedicated charger. Its function is to independently charge and monitor each lithium battery. into the battery at the same time, also called lithium battery balancing charge. Not for other purposes. 3. With this balanced charging port, there is no need to add a charging protection board to the lithium battery. 4. Regarding lithium battery discharge and overvoltage protection, you can purchase an additional lithium battery voltage monitoring module, which can be inserted into your plugss red, green, yellow and black to monitor the voltage of each battery cell. at any time. Generally, the voltage of each battery should not be lower than 2.8V before charging can begin.
There are too many lithium batteries and nickel-metal hydride batteries for model aircraft, how to choose?
1. Newqi: Newqi's miniature aircraft batteries have undergone strict chemical testing, toxicity testing, physical stability testing and reliability testing, and have an ultra-long service life.
2. Gresch: The Gresch brand treats every customer carefully with its professional production experience, mass products and strict service quality. Its miniature aircraft batteries are also deeply loved by consumers.
3. OVONIC: The main products of OVONIC brand include lithium batteries for model aircraft, batterys for model airplanes, etc. The brand's model aircraft batteries use high energy density and are lightweight. in weight and have a high explosive power.
What is the full voltage of the 4s5200mah25c lithium battery of the model airplane and the recommended C number for charging
Ni-MH and nickel-cadmium batteries and their differences:
Ni-MH and nickel-cadmium The operating voltage of the battery is 1.2 V. However, the specific volume energy of nickel-metal hydride is higher than that of nickel-cadmium batteries. Depending on factors related to the battery manufacturing process, nickel-cadmium batteries have a strong memory effect, while nickel-hydrogen batteries have a very weak memory effect. At the same time, nickel-cadmium batteries contain the heavy metal cadmium, and their use is currently prohibited. However, due to the excellent perhigh-rate discharge performance of nickel-cadmium batteries, nickel-metal hydride batteries cannot replace nickel-cadmium batteries in many power tools. Therefore, the ROSH standard temporarily allows the use of nickel-cadmium batteries in the field of power tools.
The difference between lithium batteries and nickel-metal hydride batteries:
Under the same volume, lithium batteries have larger capacity than nickel-metal hydride batteries , so their call and standby times are longer than nickel-metal hydride batteries. The price is also higher than nickel-metal hydride batteries. In addition, under normal circumstances, nickel-metal hydride batteries cannot be charged at any time, which greatly reduces their convenience.
The development of lithium-ion batteries began with lithium batteriesm, then developed into lithium-ion batteries. The first negative electrodes for lithium batteries used sheets of pure lithium. This type of lithium battery can easily catch fire and pose a danger. It is on this basis that lithium-ion batteries were developed. The negative electrode of lithium-ion batteries is made of graphite. The ionic conductor is made of lithium ions and not metallic lithium. Security is greatly improved.
The working voltage of the lithium-ion battery is 3.7V. The specific energy volume is higher than that of nickel metal hydride. Currently, lithium-ion batteries are available in aluminum shells, steel shells and flexible packaging. in different fieldsthe field occupies the market. Some markets are common, such as lithium batteries for cell phones.
However, since the function voltageThe standard of previous disposable batteries and nickel-metal hydride batteries was 1.2 to 1.5 V, the two connected in series were 2.4 to 3.0 V. Most electrical devices have already established this standard of operating voltage. Such as a portable music player, radio, etc. Therefore, in the field of civilian batteries, lithium batteries cannot replace nickel-metal hydride batteries. However, new electrical devices developed later, such as MP3, MP4, etc., all use lithium batteries as mobile power sources.
Nickel-metal hydride, nickel-cadmium and lithium-ion batteries cannot therefore be replaced by other batteries in their respective areas.
I would like to ask why the lithium battery of the model cannot be charged
The rated voltage of 4s is 14.8V, and it can reach up to 16 .8V when fully charged; batteryis not urgently needed, it is recommended to use 0.1c = 0.1 * 5200 mA = 520 mA to charge. Although 0.1c charging is slower, it is good for battery life if it is needed urgently you can use 0.3; c=0.3*5200mA=1560mA to charge.
There are two possibilities:
1.
2. Overdischarge.
Even if the battery overcharges, it will not stop charging all at once. Recharge it. After about 10 minutes, touch the charger to see if it is hot. been loaded. If it's not hot, it's been charged. This means the connector is not making good contact, meaning there is no charging at all.
The battery has been left too long. Lithium-ion batteries for model airplanes are much trickier than you might think, otherwise the cost of flying with an oil engine is about the same as flying with a gas engine. oil. un electric motor of the same level, it is because the battery is worn out due to lack of battery maintenance. The battery may be stored at the dealer for up to one month after leaving the factory. If the dealer does not maintain it, the battery will die.
Notes: Firstly, the lithium battery of model aircraft cannot be stored fully charged or empty. Second, it must be loaded and unloaded in less than a month;
