I have an Image Tank and it has performed well - no lost images that weren't my fault

One problem I have is the length of the battery cord. The cord a coiled foot long (probably 3 feet stretched), but, since I keep the IT and the battery in the carry case almost all the time, the connectors on the two are mostly 2 inches apart. I want to construct a short cord, but am having trouble locating the exact connector. Been to Radio Shack and tried various IT related web sites with no luck. No, I don't want to cut the one I have. Anyone have any help here? Thanks.
