This is a high capacity battery with moderate current capabilities.











Discharge curves tracks perfectly.





At 15A the battery gets too hot and I stop the discharge.



Oops, the battery died before my over temperature sensor stopped it. On the second battery I only tested up to 15A















Conclusion

The is a very good high capacity battery, but be careful with current draw above 10A.
