The battery Guard is an important and useful aid to protect the battery from damaging deep discharge.

Navigation devices, cell phones or on-board sockets constantly consume power, even when they are not being actively used. There is often an unpleasant shock when starting the engine – the battery has been discharged too much, the starter motor no longer turns or only turns reluctantly and the engine cannot be started.

The battery Guard is a simple and reliable solution to this problem. The Battery Guard control unit is connected directly to the battery terminals and the electrical consumers are then connected to the Battery Guard. The control unit has an adjustable, ten-stage switch: each stage corresponds to a voltage value. This level, set by the driver, defines the remaining capacity of the battery, below which the battery guard interrupts the power supply to the electrical consumer. This ensures that there is sufficient capacity to start the vehicle.

The electrical consumers can be operated without hesitation on continuous plus and the annoying switch-off at a stop is avoided.

The compact and waterproof device can be easily stowed under the seat bench, for example.

With 120 watts, the Battery Guard provides enough power for all common chargers, navigation devices, additional instruments, lighting or mobile refrigerators. The integrated fuse prevents a possible overload. Built-in overvoltage protection ensures the safe operation of all connected devices.

• The self-consumption (0.08mA) is so low that the device can remain permanently connected to the vehicle. With an average motorcycle battery with 10Ah, it would take 4 years to reach a residual capacity of 50%.

• The 10 switching stages correspond to the following cut-off voltages:

• The restart voltage is 0.3V above the selected switch-off voltage.

• For a remaining battery capacity of 80% / 20%, the following switching levels must be set:
  • Lead battery: [5] / [9]
  • Lithium-ion battery: [1] / [3]
• The Battery Guard can also be operated in reverse, e.g. in conjunction with a battery charger. In this case, however, there is no voltage cut-off.
