A C sized LSD cell, that has more than specified capacity.











The cells has a good capacity match all the way up to 10A, but they are pressed at 10A.











All the mess between 12A and 14A is my setup that hits its voltage/current limit.





Conclusion

This looks like a good NiMH battery.
