I'm trying to find the battery terminals for the excaliburs. The female parts in the battery packs. I've done some searching, but have had no luck. If it comes down to it, I guess I would have to make them, but I imagine they must be available somewhere. They do seem kind of "different" and I'm starting to wonder if they're a minelab concoction not used anywhere else but in excalibur battery packs.
