LG 18650 C4 2800mAh (Brown)



Official specifications:

• Nominal capacity: 2850mAH
• Minimum capacity: 2750mAh
• Nominal voltage: 3.65V
• Discharge end voltage: 2.75V
• Standard charge: 1375mA (0.2C)
• Max. charge voltage: 4.2V +/- 0.05V
• Max. charge current: 2750mA (1C)
• Cycle life: 300 cycles to 75% charge/discharge 0.5C
• Max. discharge current: 1375mA -20°C ~ 5°C, 5500mA (2C) 5°C ~ 45°C, 4125mA 45°C ~ 60°C
• Operating temperature: charge: -3°C ~ 50°C, discharge: -20°C ~ 60°C

This is a medium capacity cell with standard current capabilities.










Very nice discharge curves, capacity is constant up to a bit above rated current.





















Conclusion

This is a good quality cell for lower current usage (i.e. a couple of amps).
