I was wondering where I could find the 6 volt battery for a sgc 550...the one ones I am seeing do not have the plug that fits into the bottom of camera.

custom1enterprises.com sells the cables compatibly with the SG and then you just connect it to a 6V battery.
Chuck is a great guy to deal with and ships very fast - I highly recommend.

I bought this security box from him about a month ago. Ordered it on Friday and had it on Monday:
