IMO, the integrated LVC is fine if you balance during each charge. Simple perventative maintenance really. It is unlikely a pack will develop an imbalance all of a sudden unless the cells are old and tired and should be replaced anyway. Also, running at less than the max continuous C rating helps as well.

If you're using the ESC's LVC, you don't have to do anything else.

And by the way, it's not a "Quack" Monster Pro, lol. I know what you meant, it just looked funny. :)
