18650 the definition of lithium battery is: 18650 battery diameter is 18mm 65mm, cylindrical battery. 18650 Lithium Battery Parameters: Voltage: 3.6V (Conventional Universal Battery, Maximum 1C Discharge for Low Power Electrical Equipment of Electronic Products). The discharge conditions can be changed according to the situation; 3.2V (power battery can be customized according to the situation) charging parameters: 4.2V

 

The minimum discharge termination voltage is generally 2.75V, the maximum charge termination voltage is 4.20V, the capacity is 3.6V lithium cobalt oxide is 3500AMH, and the diameter is 18 + 0.2mm.

 

Xinwen lithium battery 7.4V 2000mAh 18650 lithium battery pack design:

 

Battery type: 18650-2S1P/2000mAh/7.4V

 

Nominal voltage: 7.4V

 

Nominal capacity: 2000mAh (0.2C discharge to 5.5V)

 

Factory voltage: 7.2V~7.8V

 

Product size: MAX67 * 37 * 20MM

 

Internal resistance of finished products: less than 250m ohm

 

Output mode: UL100724# red (P+), UL100724# black (P-)

 

Shelf life: 12 months.

 

Working temperature: 0~45 C (charging), -20~60 C (discharge)

 

Battery charge: charge limit voltage: 8.4V charging current: 400mA (standard), 2000mA (max).

 

Battery discharge: discharge cut-off voltage: 5.5V discharge current: 400mA (standard), 2000mA (max).

 

18650 battery charger selection:

 

Standard Charging: The battery is charged to 4.2V at a constant current of 0.5C5A (1.5A). When the charging current decreases gradually, it is charged to 0.01C5A at a constant voltage of 4.2V. The charging time is about 3 hours. Rechargeable batteries should not be permanently damaged at 0~45 C.

 

Standard Discharge: A charged 18650 battery is discharged to 6.0V at a constant current of 0.2C5A for about 5 hours after being shelved for 30 minutes at ambient temperature of 20 + 5 C. Therefore, it is suitable for 4.2V/1A lithium battery charger.

 

18650 battery usage:

 

18650 battery is a cylindrical lithium battery widely used in electronic cigarette, toys, security, rechargeable treasure, digital products, vehicle and other electronic fields.
