Enercig%2018650%202100mA%20(Gray)-Capacity

Very good discharge curves, the two cells tracks perfectly and capacity is nearly constant up to 20A.

Enercig%2018650%202100mA%20(Gray)-Temp-20.0

Enercig%2018650%202100mA%20(Gray)-Temp-30.0

Even at 30A the temperature raise is acceptable, but they do get hot.

Conclusion

For anybody that want to play with 30A or even more from a single cell, this is the cell, but the capacity is a bit limited.

This is a very good high current cell.
