Integrated Bluetooth LCD Screen
Keeping track of exactly what is happening to your auxiliary and start batteries is paramount when traveling off the beaten track. The Thunder 30A Battery Management System comes with a Bluetooth LCD interface screen, allowing you to have a better visibility of your battery’s state of charge, without looking directly at the unit. Designed for convenience, the portable LCD screen allows you to see the main and auxiliary battery voltages, auxiliary battery percentage, battery time till empty and how much current is flowing in and out of the battery. Other features include the battery fault warning symbol located in the bottom
right corner indicating any battery issues.
