I hope to receive my V2 tomorrow and as I have herd about unprotected batteries I think they are a bad idea from what I have read. I went back and read about the V2 and the batteries that are comming with it. No wear did I read if they are protected or not??? I guess I thought that the supplyer would not sell a unit with unprotected batteries but how would I know. I think that CaSH should state if the batteries are protected or not. I do not know batteries well enough to know by there numbers.
