8.4v are perfectly acceptable. You don't even need 9.6v, but if you have that/use that it's fine.
8.4v is the norm for stock guns, or even upgraded guns (I use an 8.4v large for my 380fps AUG).
9.6v for higher rate of fire with upgraded guns, but I've found my rate of fire is great, probably due to my gun being wired in deans. I don't want too high a rate of fire anyways, just wastes ammo.
