A high current and high capacity cell, that is rated for high current use.
The discharge curves tracks perfectly.
At 20A the cell reaches 81°C, but first after discharge has terminated.
At 30A I terminated due to temperature, but the cell do reach 90°C after termination.
Ignore the A charge curve, there was a glitch on my equipment.
Conclusion
This is a very good high current cell and it is rated to be used at high charge/discharge rates.
