At 30A they get a bit warmer, but due to thermal delay I do first measure it after I have stopped the discharge.

One of the cells cannot handle 15A, before it is warm and this test do not give it time to warm up.

Conclusion

I do not like these cells, they are very different. The B cell has most capacity, but need to be warm before it can deliver high current.
As 2600mAh high current cells they are bad.
