I got the fly more combo from Best Buy. Of course it could be old stock but it seems as if they fixed the issue with the batteries so long ago, there is little chance I have the old batteries, Right? Going to get some O-Rings just in case but a quick glance at the batteries show a smaller tab I think (Not much to compare to). I bought a third battery off amazon and it should be here in a few days and hopefully that will give me a better comparison (assuming it is new). O rings will be used regardless but shouldn't the old batteries be out of stock by now?
