AWT IMR18350 700mAh (Yellow)

Button top version



Official specifications:

• Rated Capacity: 800mAh (0.5CA Discharge)
• Rated Voltage: 3.7V
• Internal Resistance: <100mOh (with PTC)
• Cut-off Discharge Voltage: 2.75V
• Charge Upper Limit Voltage: 4.20±0.05V
• Charging Time(Std): 4.0hours
• Standard Charging Circuit: 0.2C A
• Charging Circuit: 0.5C A
• Standard Discharging Circuit: 0.2C A
• Fast Discharging Current: 0.5C A
• Max Discharging Current: 2C A
• Weight: about 21.5g
• Height: 65mm
• Operational Temperature: charge (0 ~ 45°C), discharge (-20 ~ 60°C)
• Storage Temperature: within 1 month (-20~ 50°C), within 3 months (-20~ 40°C), within 3 months (-20~ 20°C)

This is a high current 18350 cell. It has 6.4A continuous and 10.5A pulse rating.










The is some capacity difference between the two cells. It easily handles loads up to 5A, but has problems at 7A and cannot do 10A.















Flat top version



Official specifications:

• Nominal Voltage: 3.7v
• Capacity: 700mAh
• Standard charger: cc/cv(max ,charging rate 2A)
• Cycle Life: >1000cycles
• Max .continuous discharge rate: 6A
• Operating Dishcharge Temperature: under10 and over 60 Degree Celsius
• Dimensions: 18.15x49.82mm

Same cell as above, but this time in flat top version. It has slightly less capacity.











These cells handles 7A better.















Conclusion

The cells has very good performance at high current, but the difference between the cells means that they are best used one at a time (i.e. not in series).
