Yup, it looks like 15' is about as far as I can measure. In fact, if the distance is _too_ great, I start getting weird measurements, on the order of 8 or 9 feet. Strange.

Don't do this. First off, you won't get more current, nicads already can deliver gobs of current, enough to be dangerous. You want more amp-hours, not more instantaneous amperage.
