it will function, as long as the batteries discharge exactly equal. If one battery discharges more than the other, electrons will be flowing between the two batteries when the motor is not drawing power. I have two batteries on my bike and I just run them separately alternating between them. When I want maximum power I just switch to the one that’s the highest voltage left.
