A high capacity cell from Sanyo or is it Panasonic (Panasonic owns Sanyo). The naming match the Panasonic naming (NCR18650B for 3400mAh), but the wrapper is Sanyo style with Sanyo name on it (If you can find it, the letters are small and not very visible).











Discharge curves looks good, they track nicely.
In this test I do overload the cell, it is only rated for 7A.















Conclusion

It looks like a very good cell.
