I have heard that there are some battles being held just to get chests - like with cash battles. Is this necessary or even an advantage or can you get them in any battle.?
I think that is pointless. Just fight a regular battle and either get them or don't. As far as I know, the cash does not influence the items received from the chests.
So yes, you can get them in any battle. Arranging a box battle is just silly.
