The discharge curves looks just about perfect and with the overload protection tripping with a continous 7A load, it also looks good.

Conclusion

Evva has take a very good cell and added a good protection circuit and button top.
The result is (as expected) very good.

I run these (button top) in my BC 30 they work great, although flat tops would be better. They are a little tricky to remove
