Ok, if removing the blades doesn't cause any change, it would be interesting if, on the contrary, some extra mechanical load would be connected to the motor - will it cause less charge of the battery and if yes, how much loss. Of course, the most interesting is the case if we could measure the work of the motor: attach a known measured friction, or make it lift some weight by winding a thread; or perhaps there are some generators which enable measuring mechanical work spent for their rotation. If we measure the work, we can estimate if the COP is greater than 1.
On the other hand, concerning the battery:

I believe if we tried to use the method you suggest to measure output we would be disappointed in the results. The over unity is happening in the way the battery is being charged and not in the fan.
You believe, and is this belief well-grounded? Is it not worth experimental checking?
And the next thing, if you're sure that the amount of electicity brought to the battery is not so large and the effect derives from in the shape of signal and, therefore, way of charging, then it should be possible to build an electric converter generating a pulsing voltage similar to the one obtained from Bedini motor and to use it for charging batteries with an explicit COP>1? In this case we don't waste power for working motor and get energy "from nothing", from this extra efficient way of charging batteries?
PS If it were possible I would try to build and to check everything by myself without asking questions, but unfortunately now I don't have time for it, perhaps it is interesting to someone else who has more possibilities and/or knows more to answer these questions.
