This battery does not have any current protection and the curve only shows voltage under load. Doing 5 tests (Each takes about 100 seconds when running up to 15 ampere) did use most of the capacity in the cell. This can be seen on the last part of the last test trace.

Conclusion

The battery uses a good cell, making it a fairly safe cell, but remember it is unprotected and must not be over discharged. For uses with high current this is a very good battery and it can deliver more capacity at a higher voltage than 3100 mAh cells at high current.
