SmallHD DP4 on the way

 I bit the bullet and ordered the SmallHD DP4 monitor/electronic viewfinder. I am really looking forward to using this device with my GH2 during my stay here in the States. Problem is, the DP4 ships with a Canon LP-E6 battery plate. Since I don't own a 5D Mark II or a 7D, I don't use these batteries. I asked SmallHD about an optional Sony NPF plate (I have a bunch of small NPF's for use with my Z96 led light.) but they don't have an alternative plate as of now. They wrote they are working at it but it doesn't seem to be a priority. They should have alternatives: how hard can it be to produce such a plate?
So I am looking at a charger and a few LP-E6's. There's a lot of really cheap deals: $20 for 2 batteries and a charger. Too good to be true? I'm gambling that they are cheap because the camera doesn't 'read' the battery info. But since I won't be using them on a camera, that's fine with me. I'll let you know how they fare. And I'll tell you all about my SmallHD DP4!
