Output voltage depends on load, it looks like I got a good cell and a bad cell (Probably due to storage).

Conclusion
A very impressive high current cell (At least one of them). Modern LiFePO4 cells has gotten better, but not that much.
Notes and links
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
