EOS 7i Charger

Ok. This is if i want to charge both packs right? Otherwise, what if i want to charger my packs in single? charge my 2s2p, then charge my 3s2p....would that be better? That box you show looks different than the one that MM has?
But i understand most of what you said. But it sounds like that you're trying to explain that i can do both packs at once? That would be cool!!!
