Yes those are great batteries. I have never had any problems with batteries from CBP.
I personally don't like batteries that are soldered end to end in a stick formation. I like side by side in a flat pack. That way they are easier for me to modify, (add or subtract a battery). I also know that if you overheat a battery when soldering it you can ruin the battery. And I know that it is harder to solder batteries end to end and not get them hot. Also alot of manufactures don't solder end to end, they solder a cheap piece of metal to both and then fold them in a end to end fasion and that is not a good thing.
