Well it is a new item, and B&H doesn't yet have it in stock. Mike, the adapter you listed for BLS50 powered cameras, can it be purchased from somewhere other than B&H? I've had a couple of bad experiences with them and would like to get it from elsewhere. I don't own a BLH-1 camera, so I don't know if Olympus uses the same formulation in BLH-1 as BLN-1 (I suspect they do). I suspect this tends to make third party batteries appear to not have as much charge as the Olympus batteries, since Olympus is using the voltage produce as an indicator of how much capacity remains.

The charging and nominal voltage are higher than the standard batteries. Note, the BLN-1 batteries are 'special' in that Olympus uses a slightly different formulation then the usual lithium-ion batteries used by third party makers. The downsides of Watsons is generally the only place to get them is B&H. The charger also indicates the amount of charge left in the batteries, which I find moderately interesting.

I like Watsons, because I can use one dual charger, and just change plates to allow me to charge various Olympus and Panasonic batteries. I now use Watson batteries that Airmel said were the only ones he tested that came within 80% of the capacity of the Olympus batteries. One poster Airmel did a tear down of BLN-1 batteries a few years ago, and in his opinion, most of the third party batteries were junk. I don't know if it is specific to the BLN-1 batteries, Wasabi just had a bad batch of batteries, or Wasabi's quality control in general has suffered. There have been other postings of people getting Wasabi BLN-1 batteries that swelled. Unfortunately within several months both batteries had swelled and had to be disposed of. I bought Wasabi BLN-1 clone batteries after having good luck with Wasabi batteries in earlier cameras. Some of us do notice the difference, particularly for the BLN-1/BLH-1 batteries. I don't notice any difference in performance. I have one original and three third party. Why? The third party once are just as good.
