What? Yeah right, discharging one pack quicker than the other doesn't unbalance them, right on...
Also, that's a bit useless for anyone not using two stick packs. 7.4V max is rubbish - that's one of the reasons it's so light. By the time you add a BEC, it's not so light anymore, and you're limited to 4S max, unlike the Tekin, 150A Hobbywing, Losi and MMM, which don't need a separate BEC, and can run 6S (aside from the Losi, which'll do 5S).
