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 Brad Blake

This offers excellent value for money, works right out of the box and is highly configurable for a variety of applications, battery types and calibrations. In my case, it uses it to monitor a deep cell battery that I use as a short-term emergency backup (combined with a pure sine wave inverter). A quick way to check and see when I need to charge my battery between uses and keep track of the charge remaining during use. It can be configured for your specific battery type (SLA, AGM, Gel) and has a built-in thermistor for temperature monitoring (affecting the percent charge calculation). The thermistor is not in the module but on its own remote cable so it can be strategically placed on the battery/power supply. For camping, boating, backup power, solar power and other battery powered applications, you need one of these. The programming instructions are clearly machine-translated from Chinese, so they leave something to be desired but are still clear enough to follow.
