Manufacturer description

The DROK RV Battery Monitor gives you a dedicated readout for any battery bank from 10V to 100V. It covers 12V, 24V, 36V, 48V, 60V and 72V systems, so the same meter works on an RV house bank, a golf cart, a boat, an ebike or a car. The color LCD shows battery capacity, voltage or temperature. You switch between them with a single key, and the screen stays readable in direct sunlight. An external 30cm temperature probe sits directly on the battery and reports real-time temperature in Fahrenheit. The meter also watches the battery for you. A buzzer sounds on low voltage and on…

SpecPicks Verdict
