I just acquired a JVC GR-SXM46EG, i realise its not exactly a new camera but it seems fine for my use and saves me a few hundred quid in buying a new one.

Does anyone knw if i can get one of those battery packs or battery blocks (i dont know what you call them), the ones that you plug into the camera and the power lasts for hours and hours, pretty much all day on previous cameras i have had, where can i get one that will fit ??
