[size=+3]Samsung INR18650-33G 3150mAh (Blue)[/size]

Official specifications:

Typical capacity: 3150mAh Minimum capacity: 3000mAh Charge voltage: 4.20V Nominal voltage: 3.60V Charging method: CC/CV Standard charge current: 975mA Maximum charge current: 3250mA (Not for cycle life) Maximum continuous discharge current: 6500mA Maximum pulse discharge current: 9750mA Discharge cut-off voltage: 2.5V Cycle life: 500 cycles to 75% with 975mA charge and 3250mA discharge. Operating temperature: charge: 0°C ~ 45°C, discharge: -20°C ~ 60°C Storage temperature: 1 month: -20°C ~ 60°C, 3 months: -20°C ~ 40°C, 1 year: -20°C ~ 45°C

This is a high capacity cell with limited current capabilities.

The discharge curves matches fine, but the cell is not for high current, even 10A is over the limit, but then it is not rated for more than 6.5A

[size=+3]Conclusion[/size]

It is a good quality high capacity cell, but watch out for charge current.

[size=+3]Notes and links[/size]

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.

How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries Compare to 18650 and other batteries
