The cells tracks fine. Compared to the usual LiIon the voltage is fairly low, but it stays mostly constant during discharge.

A typical LiFePO4 charge curve.
Conclusion
The cells looks like good LiFePO4 cells, but a 4.2V LiIon cell in this size can have about double the energy.

One reason can be lifetime. I did not find any specifications for this cell, but LiFePO4 can usual handle many more cycles than 4.2V LiIon.
Another reason can be the considerable higher self ignition temperature.

Or simple the device needs LiFe cells

For flashlights they are not good, mainly because the voltage doesnt match with what the LED needs without boost converter
