This is a high current battery with good capacity.











The two cells tracks nicely and the capacity loss is not very large up to 20A.





At 20A the cell get rather hot.



And at 30A I had to stop the discharge due to temperature.















Conclusion

This is a good battery and the rewrap has not changed that.
