DC 12V 24V 36V 48V 72V Battery Meter, Battery Capacity Voltage Monitor Gauge Indicator, Lead-Acid&Lithium ion Battery Tester, for Golf Cart RV Marine Boat Club Car Motorcycle - With Alarm, Green

I bought this to integrate into a motor controller build for a trolling motor. It works great and is highly visible day or night. I like knowing the condition of my battery throughout the period of use and this makes that possible with sufficient accuracy. I liked this meter so much that I bought two more to use in other upcoming dc power projects.

Only one meter arrived.

pas rien pour fixer pour le compteur et aucune méthode de fixation Malheureux..

The item doesn't read the voltage and when I asked about a different one they never replied. Plus if I want to return the item I have to pay have the cost of what i paid for the item

I didn't find the "advanced" menus, even after multiple attempts, but I didn't see them as offering anything that useful either, as I just wanted a display of the battery state for my kids powerwheel when I upgraded it to use a 40V battery, which for that, it does a splendid job of. The display is clear, easy to read, and shows what I want to know. %, Voltage, and a "1-6" segment display of battery life. So I can really easily tell at a glance how close my kid is to killing the battery. (So far, VERY FAR...)
