This is a older high capacity cell (Datasheet from 2012), it is not designed to deliver high current.

The discharge curves matches very nicely, datasheet only shows discharge curves up to 2C, i.e. around 4A, but it can handle more.

[size=+3]Conclusion[/size]

This was a very good cell some years ago, today both the capacity and the current ability is rather low.

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
