What is the 18650 cell? What are its characteristics

　　1. It has a large volume.

　　In general, the volume of 18650 lithium battery cell is generally between 1800mAh and 2600mAh, while the volume of general lithium battery cell is only about 800Mah. If this lithium battery cell is combined to form the 18650 lithium battery, then the 18650 lithium battery can be easily increased by 5000Mah.

　　2. Long life

　　The 18650 lithium battery cell has a long service life. In all normal applications, the service life of the circulatory system is more than 500 times, more than twice that of ordinary lithium battery cells. The battery cathode material is the 18650 lithium battery cell of lithium iron phosphate battery. In all normal applications, the frequency of the circulatory system is up to 2000 times.

　　3. High safety factor;

　　Lithium battery cells with high safety factor, non-toxic and zero pollution verified according to RoHS; Various safety factors are achieved at one go, and the frequency of circulation system exceeds 500 times; Good heat resistance, charging and discharging efficiency reaches 100% under 65 ℃ standard. In order to better prevent short circuit fault of lithium battery cell, the positive and negative stages of 18650 lithium battery cell are separated. Therefore, the probability of short circuit fault has been reduced to the minimum. The lithium battery protection board can be added to prevent overcharging, overcharging and discharging of the lithium battery cell, and prolong the service life of the lithium battery cell.

　　4. It is high voltage.

　　The working voltage of lithium battery cell 18650 is generally much higher than that of nickel cadmium and nickel hydrogen lithium battery cells.

　　5. No memory.

　　6. The internal resistance is small;

　　Because the internal resistance of the 18650 lithium battery cell is small, like the 18650 bipolar lug with multiple output power, its internal resistance can be less than 25m Ω.

　　7. It is widely used in assembly.

　　Lithium battery pack with different working voltage and different volume can be used in series, parallel and parallel connection.

　　8. Wide range of use

　　Because the specification is fixed, the 18650 is small, light and large. It becomes the best choice for many power consumption machines and equipment.
