You got that right!

It's possible we're seeing higher average amp draw per battery, but then it all depends on the driver, doesn't it? I tend to drive the FS pretty conservatively. Even though the Jetta these batts are coming from is probably a 120 volt system, if it's driven faster and accelerated harder it could all work out to be the same.

I never did any brush timing vs. efficiency testing because (1) I have no easy way to hold enough other variables constant, and (2) we don't have instrumentation that would make data collection easy. Just look at the "fuel log" for this car and you can see efficiency swings pretty wildly. So there's no way I'd be able to see the effect of changed brush timing just by fiddling with it and using the car.
