No, this is not possible, as you will always be on the safe side with the Battery Monitor. Three-level discharge protection prevents you from ever draining the vehicle battery. The principle is rather straightforward: If the battery charge drops below a certain level, the power supply to the portable fridge/freezer is automatically cut off. You can choose one of the three pre-set levels on the control panel or in the App:
LO: The appliance switches off at 10.1 ± 0.3 V
ME: The appliance switches off at 11.4 ± 0.3 V
HI: The appliance switches off at 11.8 ± 0.3 V.
Low battery protection
This mode is particularly well suited to the use of auxiliary batteries, which are not relevant for starting the vehicle.
Medium battery protection
This mode is suitable for the vast majority of situations. It is particularly well suited for when a modern starter battery is in place.
High battery protection
This mode is suitable if, for example, older car batteries are used, which may be relevant for starting the vehicle.
