A quick look at an inexpensive new test gadget I purchased to help me review RV battery and power systems. The Koolertron (aka Junctek) battery monitor has a 400 amp shunt, LCD, and Bluetooth app. It’ll display a plethora of information for me like the voltage, amperage, wattage, kilowatt hours, amp hours, temperature, and more.
So far I have to say I like it. The little LCD screen is bright and clear, and the readings appear accurate. The Bluetooth phone app is handy and has a good signal range. Look for my product review after I’ve had a chance to use it for a while.
