Review on 🔋 Digital Battery Capacity Monitor, DROK 10-100V 24V 36V 48V Power Tester Meter, Battery Status Remaining Percentage Level Voltage Fahrenheit Temperature Indicator Gauge for Marine RV by Kevin Kue

Installed on my golf cart. After figuring out how to program it, I finally got everything set up. It seemed to work perfectly and accurately. However, after switching off the car, ALL PROGRAMMING WILL BE LOST! In times of mature electronics, this is unforgivable. Something this simple shouldn't lose all programming when you turn off the power. All it needs is EEPROM to store data instead of RAM. I don't want to turn it on unattended, it's a fire saver, especially with non-UL listed electronics. should have known Almost all electronic, rubber or plastic products from China are cheap and poor quality with a very short lifespan. I have a turntable that I bought in 1984, made in Japan, still works like new and is 35 years old. This thing won't last 3 years.
