I think it's a good idea to have a few extra drawers for various bit sets that you have, which I'm thinking will include a set of Brad point bits, twist bits, spade bits, possibly auger bits, Forster bits, vix bits, countersinking bits / pilot bits plus a set or two of driver bits for Philips screws, straight screws, square screws and the like. It would be handy to have this organizer somewhere relatively close to the drill press since many of the bits would be used there from time to time. It would also be helpful to have an additional removable drawer in or attached to the side of the organizer -- perhaps with a magnetic strip or two inside -- that could be used to load up the bits that you are going to be using with a hand drill at some other location in your shop or home so you didn't have to run back and forth between the organizer / storage area and the work project. You could just load the bits that you need for the specific project in the additional drawer and take it to the worksite. Or you might have some kind of a removable container or drawer that you hang on the side of the organizer on a French cleat or attach with a magnet. The top of the organizer would be a good place for the extra batteries and the charger(s), so long as it wasn't so high that it was tough to exit access if you had to lean over a workbench to get to it. I think chargers and batteries on top is plenty, if it's open storage for miscellaneous tools, once it starts, it just keeps attracting additional stuff that you can't find when you're looking for it later.
