Norsk Guardian 4+

Monitor and control your boat’s battery in a smartphone. Oversee charge, voltage and resistance, and never ever be caught up by battery problems in the middle of the sea!

Norsk Guardian is your app for safe trips on the water. It will help to avoid troubles at sea caused by battery problems through the real-time monitoring of the battery status.

Each battery has its own Bluetooth module, thanks to which all data will be instantly transferred to your phone.


With Norsk Guardian, it’s convenient to monitor the status of your batteries in real time by tracking the charge, voltage, and resistance. If the indicators are below or above the norm, the application will warn you with a push notification telling the battery is out of order and requires maintenance. After that, you can contact Norsk for warranty service.


For your convenience, batteries can be grouped (for example, "My boat", or "My father’s boat"), so you can monitor the batteries on several boats at the same time.


Before each sailing, we advise you to check the battery status, this will help you avoid unsafe situations on the high seas and make your trip comfortable.
