[size=+3]Vapcell INR18650 2800mAh (Black) 2018[/size]
Official specifications:
This is high current 18650 batteries with good capacity.
Very nice discharge curves with a good match and capacity drops slowly with higher current.
I forget to put the temperature sensor on the A battery
By accident I started a "small battery test" instead of a normal test for the A cell. This means it will include a 100mA discharge, charging current is 0.5A and this test here only goes to 7A
See text above.
[size=+3]Conclusion[/size]
This is a very good high current cell.
