If my understanding is correct, there is a BCM (battery control module) that regulates the charge flow so that the front starter battery is charged if needed when rear battery is being charged by electric charger, thereby eliminating need for 2 chargers, just the rear is needed to maintain both batteries.

If it is possible start the car up a few times during the winter and take it for a short trip. That would be best way to ensure that your Mercedes-Benz stays in excellent shape.
