18650 battery 10000mah

　　What is 18650 battery?

　　It refers to the appearance specification of the lithium battery cell, which is the standard model of the lithium battery cell that the Japanese SONY company originally decided to save costs. In the 18650 core, the data of 18650 represent the appearance size: 18 means a diameter of 18mm, 65 means a length of 65mm, and 0 means a cylindrical cell. General 18650 batteries are divided into lithium-ion batteries, lithium iron phosphate and nickel-metal hydride batteries.

　　Features of 18650 batteries:

　　1. It is large in volume.

　　Under normal circumstances, the capacity of 18650 lithium batteries is generally between 1800mAh-2600mAh, while the capacity of ordinary lithium batteries is only about 800Mah. If these lithium batteries are combined to form 18650 lithium batteries, then 18650 lithium batteries can easily increase to 5000Mah. .

　　2. Long life

　　The 18650 lithium battery has a long service life. The service life of the circulation system can reach more than 500 times during normal use, which is more than double that of ordinary lithium batteries. The positive electrode material of the battery uses 18650 lithium batteries of lithium iron phosphate batteries, which can be used normally The time circulation frequency reaches about 2000 times.

　　3. High safety factor;

　　High safety, non-toxic, and zero-pollution lithium battery cores certified by RoHS; various safety factors in one go, cycle frequency exceeds 500 times; heat resistance is good, and the charging and discharging efficiency reaches 100% under the standard of 65 degrees. In order to better prevent the short-circuit failure of the lithium battery cell, the positive and negative stages of the 18650 lithium battery cell are separated. Therefore, the probability of its short-circuit fault condition has been reduced to a minimum. A lithium battery protection board can be added to prevent overcharging and overcharging the discharge core, and it can also extend the service life of the lithium battery.

　　4. It is high voltage.

　　The working voltage of lithium battery cell 18650 is generally lower than that of nickel-cadmium and nickel-metal hydride lithium batteries.

　　5. No memory.

　　6. Small internal resistance;

　　Because the internal resistance of the 18650 lithium battery is not large, like the output power multiple type 18650 bipolar ear, its internal resistance can be below 25mΩ.

　　7. It is widely used in assembly.

　　Lithium battery packs with different voltages and volumes can be connected in series, in parallel, and in parallel.

　　8. Wide range of use

　　Because the specifications are fixed, the 18650 is small in size, light in weight and large in volume. It has become the first choice for many power-consuming equipment.
