One of the maxamps lipos has a small amount of damage to it on the end. Otherwise they seem to be hold voltage reasonably well. What did you sue them in? Did they puff on you a bit under load?

You said not to charge them before sending them so I didn't. I have stored them always fully charged and balanced. There's now about half years iirc from charging them.
Robbe lipos swelled quite much when I used them in my boat about 2 years ago. Haven't used them since, just charged them time to time.
Same thing twith MA lipos, both puffed. The other one which has electrical tape on it puffed more. And last time I test it it puffed again, but not so much was using it parallel 16000mah 11.1V
But thats odd you didn't notice anything else than miss balancing in the cells..
Try pressing that Ma lipo where's electrical tape, does it feel a little soft to you?
You can test drive them if you like or got time.
But if you can't find anything to fix with them you can sell them and split the moneys or something.. But I have seen my own eyes all of them puffing and only the MA lipos I have used in extreamely rare cases after that. Puffing I don't mean it has swelled to a balloon but so that it is noticeable..
Hope you get something from that
Edit:.
Puffing was the reason to move on A123 batterys, but now Im thinking trying lipos again, I think Im old enough and learned my lesson
