Always sufficient power
With the E-Volt module, you can see in the E-Trailer app exactly how full your onboard battery of the motorhome or caravan is charged. If the voltage becomes too low, you will receive a warning through the E-Trailer app, enabling you to take measures before running out of power during your camping holiday. The E-Volt module can be adapted to any type of battery: lead-acid, AGM, or lithium battery. The values are given with precise accuracy (in percentage) rather than incrementally.
