Very clever -- just bypass the controller and use another controller near the battery! I'm not sure I will do that -- depends on the cost and my lack of skill -- but that is definitely thinking outside the box.
It's interesting (in a 30,000 foot way) to see myself as a captive of my own assumptions, for example: "Well, the controller is permanently attached, so I guess I am stuck with it."
It is very hard to force myself to think in a non-linear way: what if we ignore the existing controller?? Once someone else points out the obvious alternative (usually DW), I feel humbled. It is not a pleasant sensation.
