The Power pack is available, but this is not supplied with the 510v "laminate" pack, which offers astonishing recycle times. I think that the Sunpak 510v nicad pack will fit, as the Pentax Power Pack is more than likely a rebranded SunPak item. I am trying at present to get ToCad in Japan to supply measurements for the cell, as we have a Pentax Power Pack in for someone in your position.
