Review on 🔋 SUPNOVA Battery Monitor: Versatile Voltage & Capacity Tester with Buzzer Alarm - 12v to 72v Car & Golf Cart Battery Indicator Meter by John Duffield

The FE-LI default range does not match my LiFePO4 battery range, but I was able to set my own range. The screen is bright and easy to read. My only "complaint" is that setting a custom range causes the percentage shown to be misleading. For my LiFe battery, 13.4 is 99%, 13.3 is 90%, 13.2 is 70%, and 13.1 is 40%. It doesn't match the display percentage at all. For the price, however, I have no complaints and SOC will at least give me a rough number. The supplier responded quickly to questions. Consistently great product and support experience.
