Bean - B&H has some various cables with the hirose connector already wired in, probably don't have them with the RC connector but you could check it out. I know fozzy or some else had mentioned that they bought the dummy cells for cheap on ebay, allowing one to wire up 7.2v cells instead, maybe something to look into.
i've heard they are a bitch to work with too since they are so small, FWIW
