If everything I've read so far is true this camera is 9 volts and there is currently no battery pack or solar option available. It seems to me unless you're emptying your pockets buying 48 lithium batteries (I have 4 cameras) then going out and changing batteries every 6-12 weeks kind of defeats the purpose of the Cuddelink system doesn't it? You would think it would be a better marketing strategy to have the accessories available when the camera was released. I suppose with some ingenuity the solar chargers I have with 12 volt battery back ups could be modified with a 9 volt regulator since there's a port on the back of the camera for solar.
