Maxxamps batt always out of balance

[transtalon]

I was getting tired of this 3S 8000 MAH 25C cell that I got from Maxamps from being out of balance everytime I run it and I decided to open it up. I found that there is a pair of 4200 MAH 25C cell but the other two pair was an older one and it is a 4000 MAH batts. I can't believe this is how they manage to match each cell during assembly. I am just venting here but just warning the new guys on my experience. I am not bashing them but just letting you guys what I discovered today.
