Review on 🔋 Battery Monitor and Voltage Capacity Tester for 12V, 24V, 36V, 48V, and 60V Iron-Lithium & Lead-Acid Batteries – Battery Capacity Indicator with Voltage Capacity Percentage by Adam Boesel

This is a quick and easy battery gauge to let you know the status of your battery (or battery). Supplied with 2 sets of self-tapping screws (1 flat, 1 rounded) and easy to connect. Turn on the device for normal use without pressing the button. Displays the battery bar (battery flashes when it is very low) with usage percentage. The key then toggles between percentage and raw voltage display. An important note: When plugged in, the blue backlight goes out after 10 seconds. However, the LCD and monitor remain operational until the power is turned off. This may be important to those discussing its use for specific applications. Programming is easy: hold the button down when you first turn on the device (or to reprogram it) and it will start displaying the current mode. Then you can press the button to switch modes. The mode is a number (#) and a letter (P/C/F). For P (lead-acid), the test is performed at 12 V * #. For C(Lith)/F(Iron-Lith) the test is 5+(10*#). Disable when you're in the mode you want and it remembers that.
