When the motor finally gets going faster, it will deliver a voltage that is higher than the battery voltage. But by then the motor is producing so much power that you would never notice any load that the charger might draw. It is only 1 or 2 watts max out of 1500 watts.
Yes, possible the battery makes a difference. However I'd go nuts switching such a system around the various bikes I use regularly. For me a simple bike light in my backpack does the job. Rarely ever get caught out after dark so never worry about charging/discharging. Same batteries 3 yrs now.
What's 1500 watts? Not the magneto.
