If you're patient you can get the cables on ebay for more reasonable prices.
Obsolete USB cables = $0
Soldering iron and heatshrink I already own = $0Three short EW-50s required for my setup: one for the pair of plugs for the derailers, another for the shifters, and the third for the battery and to be grafted onto the charger. The A junction is gutted and hidden inside the stem, which has a little hole plugged with hot glue that looks like a LED, showing the light from the actual LEDs, and the mode/set button is remotely mounted under the back edge of one of the hoods. My Di2 is as invisible as the semi wireless one.
Although I have to concede that it's fiddly as fuck between the steerer and stem; if I want to separate the two I have to unsolder a join under the top cap, since any sort of plug there just won't fly.

That said, I've cut and soldered two genuine cables to make internal Di2 happen on a non-compatible frame and they've not failed after several years and thousands of miles.
