Re: what if I use household 9v batteries?
Size matters for the capacity of the battery. Batteries are rated on an amp/hour basis. A 9v smoke detector batter is much below 200 miliamp/hours.
Also batteries have a peak amperage that they can give off in an instant. This peak amperage depends greatly on the capacity of the battery. A 9v probably couldn't even give enough amperage burst to power an unloaded cim motor.
So, unless you wire about 100-9 volts in parallel, then I wouldn't use them for anything more than they are designed for.
