The discharge curves matches very well, but the battery is not good at high current.

Conclusion
This is a good battery, but capacity and current handling cannot match the last generation cells.
Notes and links
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
How is the test done and how to read the charts
How is a protected LiIon battery constructed
