Battery Computers / Displays

Want to buy a battery computer for your modern motorhome or car? Look no further, because at Offgridtec you will find what you are looking for! With its high-quality components and functions, our battery indicator will help you keep your battery in optimal condition for many years.

Mobile battery computers for motorhomes, cars & co.

A battery computer measures the battery voltage and displays the condition of your battery. It monitors the voltage and current in the battery and helps you determine how much charge is left in the battery.

Offgridtec's battery computers are compatible with a wide range of devices, such as a variety of equipment in:

  • Motorhomes
  • Cars
  • Motorbikes
  • Boats and other vehicles

Battery indicators are particularly important here

If you have already invested in an expensive lithium battery and want to know its capacity, you cannot do this without a battery computer. Due to the small voltage difference between fully charged and empty lithium batteries, it is not possible to obtain reliable information from voltage values alone. Nevertheless, to protect your high-priced battery from unnecessary damage due to deep or overcharging, you should definitely invest in a battery computer.

LED battery indicator 12V incl. Bluetooth and other features

The Offgridtec battery computer can be used with a wide range of batteries, e.g. 12V, 24V and even 48V batteries. Another great feature of our battery monitors is their Bluetooth connectivity. You can pair many of our devices with your smartphone or tablet and get detailed data on battery performance from anywhere. Bluetooth connectivity also makes it easy to share information with technicians should you ever notice a defect.

Our battery computers make it easy to monitor and maintain your battery to maximise its life and performance. They provide real-time information about the battery's current levels, voltage and temperature, as well as alerts when it should be recharged.

Offgridtec also has a wide range of other battery accessories to help you customise your electronic system and get the most out of your battery.
