Review on DC Multifunction Battery Monitor Meter, LCD Display 0-200V & 0-100A, 🔋 Ideal for 12V/24V/48V RV/Car Battery - Digital Solar Power Meter, Multimeter Ammeter Voltmeter by Eddie Sanchez

Forget for a moment the terrible instructions that you have to read again and again through the eyes of a translator and a very clumsy software interface. This device does not calculate charge and discharge values for power and current. Everything has a positive value, making it as useless for determining the state of charge of my boat battery as some of these reviews. In any case, a real battery monitor is not that complicated. You enter the size of your batteries, program either the battery type or charge voltage settings and voila! You can get more exotic results using Peukert's coefficient, temperature correction, etc., but the above is fine for most applications. This block is not.
