The Hummingbird Battery Monitor is your best friend when travelling with your caravan, boat, fridge, or solar accessories, making it a breeze when keeping an eye on your battery levels.
Using radio frequencies and no wires, this easy to install monitor measures your battery voltage of up to four remote batteries at a time. Displaying the voltage levels on a remote colour screen, alarm levels can be customly set to warn you on depleting battery levels, essential for when you’re carrying a fridge on a hot weekend away.
This battery monitor uses a long range RF technology, meaning the communication is reliable in all configurations of car and trailer. Batteries can also be given names that are relevant to the application for easy control. Ultra low voltage transmitters are able to be left permanently connected to batteries and do not need to be switched off when not in use, this includes both 12V and 24V batteries.
