This is one of the new high capacity cells.
The discharge curves has good tracking.
At 15A the B track stops just after 2.3Ah, this is because my battery holder melts (I hope this is fixed now).
15A is definitly too high current for this cell. The cell temperature is above 75°C (25°C ambient + 50°C temperature raise). Logfile says 87°C for A cell.
On this chart it is obvious how the heat improves the performance at 15A.
Due to the melted battery holder I did only do this for one cell.
The cell looks very good, it has lot of capacity and can handle some current, but I will not recommend it above 10A.
