has introduced a lot of knowledge about lipo battery in previous articles. Today I will answer some common questions about 1s lipo battery 70c
, as well as 1s lipo battery 70c usage precautions and life-span factors.
1s lipo battery 70c FAQ
What is the electrochemical principle of 1s lipo battery 70c?
1s lipo battery 70c The main component of the positive electrode is LiCoO2, and the negative electrode is mainly C. When charging,
Cathode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Negative reaction: C + xLi+ + xe- → CLix
1s lipo battery 70c Total reaction: LiCoO2 + C → Li1-xCoO2 + CLix
The reverse reaction of the above reaction occurs during discharge.
What is the capacity of 1s lipo battery 70c?
The capacity of 1s lipo battery 70c is divided into rated capacity and actual capacity. The rated capacity of the 1s lipo battery 70c refers to the design and manufacture of the 1s lipo battery 70c which stipulates or guarantees that the 1s lipo battery 70c should discharge the minimum amount of electricity under certain discharge conditions.
The following article about lipo battery capacity can help you understand
What is the capacity of 11.1v lipo battery?
The IEC standard stipulates that the nickel-cadmium and nickel-hydrogen lipo batteries are charged at 0.1C for 16 hours and then discharged to 1.0V at 0.2C under the environment of 20℃±5℃. . As for the 1s lipo battery 70c, it is stipulated to charge for 3 hours under the charging conditions controlled by normal temperature, constant current (1C)-constant voltage (4.2V), and then discharge the amount of electricity released from 0.2C to 2.75V as its rated capacity. , and the actual capacity of 1s lipo battery 70c refers to the actual power released by 1s lipo battery 70c under certain discharge conditions, which is mainly affected by the discharge rate and temperature (so strictly speaking, the capacity of 1s lipo battery 70c should specify charge and discharge condition). The unit of 1s lipo battery 70c capacity is Ah, mAh (1Ah=1000mAh).
What is the discharge residual capacity of 1s lipo battery 70c?
When the rechargeable 1s lipo battery 70c is discharged with a large current (such as 1C or above), due to the "bottleneck effect" of the internal diffusion rate caused by the excessive current, the 1s lipo battery 70c has reached the terminal voltage when the capacity is not fully discharged. , and then continue to discharge with a small current such as 0.2C, until 1.0V/branch (NiCd and NiMH 1s lipo battery 70c) and 3.0V/branch (lithium 1s lipo battery 70c) The released capacity is called residual capacity .
What is the internal resistance of 1s lipo battery 70c?
Refers to the resistance of the current flowing through the 1s lipo battery 70c when the 1s lipo battery 70c is working. It consists of ohmic internal resistance and polarization internal resistance. 1s lipo battery 70c has a large internal resistance, which will reduce the discharge working voltage and shorten the discharge time. The size of the internal resistance is mainly affected by factors such as the material of the 1s lipo battery 70c, the manufacturing process, and the structure of the 1s lipo battery 70c. It is an important parameter to measure the performance of 1s lipo battery 70c. Note: Generally, the internal resistance in the charging state is used as the standard. To measure the internal resistance of 1s lipo battery 70c, you need to use a special internal resistance meter to measure it, but not with a multimeter ohm gear.
1s lipo battery 70c use precautions
01) Before use, please read the 1s lipo battery 70c manual carefully;
02) Electrical appliances and contact parts of 1s lipo battery 70c should be clean, wiped with a damp cloth if necessary, and installed according to the polarity label after drying;
03) Do not mix the old and new 1s lipo battery 70c, and the same model but different types of 1s lipo battery 70c can not be mixed, so as not to reduce the use efficiency;
04) The disposable 1s lipo battery 70c cannot be regenerated by heating or charging;
05) 1s lipo battery 70c cannot be short-circuited;

06) Do not disassemble and heat the 1s lipo battery 70c, or throw the 1s lipo battery 70c into water;
07) When the electrical appliances are not used for a long time, the 1s lipo battery 70c should be taken out, and the switch should be turned off after use;
08) Do not discard the waste 1s lipo battery 70c at will, and put it separately from other garbage as much as possible to avoid polluting the environment;
09) When there is no adult supervision, do not allow children to replace the 1s lipo battery 70c, and the small 1s lipo battery 70c should be placed in a place that children cannot reach;
10) 1s lipo battery 70c should be stored in a cool, dry place without direct sunlight.
Factors affecting the service life of 1s lipo battery 70c
When choosing a charger, it is best to use a charger with correct termination of charging devices (such as anti-overcharge time device, negative voltage difference (-dV) cut off charging and anti-overheating induction device), so as not to shorten the 1s lipo battery 70c due to overcharging service life. Generally speaking, slow charging can prolong the life of 1s lipo battery 70c more than fast charging.
a. The depth of discharge is the main factor affecting the life of the 1s lipo battery 70c. The higher the depth of discharge, the shorter the life of the 1s lipo battery 70c. In other words, as long as the depth of discharge is reduced, the service life of the 1s lipo battery 70c can be greatly extended. Therefore, we should avoid overdischarging the 1s lipo battery 70c to very low voltage.
b. When the 1s lipo battery 70c is discharged at high temperature, the service life of the 1s lipo battery 70c will be shortened.
The following article about the charging and discharging of lipo battery has a detailed introduction, and the partners who need it can refer to it by themselves:Lipo battery 4s charging and discharging principle, be sure to store it well!
c. If the designed electronic equipment cannot completely stop all the current, if the equipment is not used for a long time without taking out the 1s lipo battery 70c, the residual current will sometimes cause the 1s lipo battery 70c to be excessively consumed, causing the 1s lipo battery 70c to overheat. discharge.
d. Mixing 1s lipo battery 70c with different capacitances, chemical structures or different charging levels, as well as old and new 1s lipo battery 70c, will also cause the 1s lipo battery 70c to discharge too much, and even cause reverse charging.
If 1s lipo battery 70c is stored at high temperature for a long time, its electrode activity will be attenuated and its service life will be shortened.
Well, the above is the whole content of today. I believe that after reading the whole text, everyone has some understanding of some common problems of 1s lipo battery 70c and the precautions for charging and use.
