Monitor more and go further with REDARC's additional Wireless RF Battery Monitor Transmitter by REDARC Hummingbird. When paired with the Hummingbird RF Battery Monitor, this accessory allows you to wirelessly monitor up to 16 batteries.


Forget about complicated and costly installations, simply plug the RF Battery Monitor into the vehicle’s accessory socket and permentatly connect the transmitters to your batteries to monitor up to 16 batteries on the go.

This wireless battery monitor featuring RF wireless technology is perfect for monitoring voltage in a single application like a 4WD, car or caravan, or with a large fleet of batteries in the commercial or mining industry. Through long range RF technology, the Wireless Battery Monitor uses ultra-low power transmitters to reliably communicate voltage levels in 12v and 24v battery configurations. 


As it features a low current draw, there is no need for the system to be switched off when not in use. Precisely monitor up to 16 batteries individually on the easy-to-read screen with a quick drive by. As each battery can be given a unique name, the RF Battery Monitor makes it wasy to identify the status of the “loader”, “forklift”, or “fridge”, “caravan”, and “main battery” on the fly, so you know when to put the solar panels out or go for an extended drive. 


Setup is as easy as attaching the red and black terminals on the transmitter to the battery that needs to be monitored, and then pairing with the transmitter and remote monitor. Once set-up, know when something has gone wrong by setting minimum and maximum voltage alarm levels that warns the user with an easily identifiable colour indicator and an optional buzzer when pre-set limits have been reached.

Quickly identify unwelcome battery conditions, avoid costly downtime, and extend the life of your batteries with REDARC Hummingbird.
