My desire is to reduce the current consumption, by upgrading the motor, without reducing the air flow (much if at all.
It should be, not reduce the airflow at ALL!!
The furnace is matched to the motor, tested and certified with that motor.
Replacing it with something else could result in a dangerous situation.
Having said that.. What exactly are you trying to accomplish?
My guess is that like all of us, you want the battery(s) to last longer.
My suggestion is to use the tried and true methods.
LED lighting. This will actually save MORE power, and be easier/cheaper to do.
You are hoping to cut the furnace draw in half. While I doubt that is possible, lets look at just what that will save you.
3.5 Amps.... While the furnace is running. But it doesn't run all the time. on very cold nights it may run 50% of the time. So a 10 hour night with super efficient motor would only save 17.5 AH.
And that is IF you can get such a motor.
It is very easy to save more than that with LED lighting.
