Battery Monitors

The battery is a key component in most of today's electrical devices, so you should not underestimate its importance. A high-quality battery monitoring system can help you detect battery malfunctions and prevent problems before they become bigger. At Offgridtec, we do everything we can to keep your batteries operational for as long as possible. That's why you'll find a wide range of battery monitoring products in our online shop, so you can always be confident of a well-functioning battery.

What is battery monitoring for?

Battery monitoring systems allow you to keep an eye on your battery's performance and detect irregularities in usage and power consumption. This also allows you to effectively track your energy consumption and reduce your energy costs in the long term.

Battery monitoring systems at a glance

Different systems are specifically designed for different purposes, as well as for different sizes and performance. So when buying, make sure that your new surveillance system meets your specific requirements. Our experts will be happy to advise you on your selection and help you find the right model.

We carry different battery monitoring systems, such as battery monitors and battery monitors. A battery monitor provides you with precise data on parameters such as battery voltage, used ampere hours, state of charge and remaining runtime. In addition, some models are equipped with an integrated Bluetooth module that allows you to access many functions and status reports of the battery computer via a free app.

  1. What is battery monitoring for? With a battery monitoring system, you can monitor the performance of your battery and detect irregularities in usage and power consumption. This allows you to track your energy consumption and reduce your energy costs in the long term.
  2. What does a battery monitor do? A battery monitor is a compact device that can be retrofitted to pretty much any vehicle. It is connected to the vehicle battery and monitors its state of charge.
  3. How does a battery monitor work? The battery monitor works via a shunt (resistor) that is attached directly to the supply battery and measures incoming and outgoing currents. From this, it calculates the current state of charge, the ampere hours (Ah) already consumed and the remaining runtime.
  4. What is voltage monitoring? The purpose of an electronic voltage monitor is to automatically check whether a circuit is operating within a specified range of the operating voltage. If this range is not maintained, measures are automatically initiated, such as data backup, system shutdown or a reboot (restart).
