This is a low capacity high current battery.











The discharge curves looks good, they track fairly well and capacity is fairly constant independent of load.





Even at 30A the cell do not get too hot, probably because the discharge time is fairly short.















Conclusion

This is a good high current battery, but from an older design with less capacity.
