Renogy 500a battery monitor6/17/2023 ![]() Note: when replacing the battery, be sure to set the new values in the battery monitor. These settings are set via controls on the right of the LCD screen. Just in case, it is also recommended to check the following video from Renogy:Īfter connecting the battery monitor, there are a few things the user has to set, including the Battery Capacity (Ah), Full Capacity Battery Voltage (V), Zero Capacity Battery Voltage (V), Shutdown Voltage (V), Low Capacity Alarm (Ah), and the Battery Attenuation Ratio (%). Note: Again, the shunt ("B-" connector) is connected to the battery's negative terminal and NOT to the positive. When the battery monitor arrives, it must be properly connected to the battery (or battery pack) according to the following connection diagram:Īs one can see in the connection diagram, the shunt is connected in series with the battery (so that it can measure the current) to the battery's negative terminal and is connected with the battery's positive terminal via B+ wire (so that it can measure the voltage and to power the unit itself). How To Connect and Program The Renogy RBM500 Battery Monitor? When the unit arrives, the package contains:Īlso, the package contains an Owner's Guide, which is not too long (~10 pages), and when the unit arrives, it should be thoroughly read in order to get accustomed to the battery monitor and especially the connection diagram. Renogy RBM500 battery monitor features a very good accuracy of ☑% for measured current, voltage, and capacity.Īlso, the Renogy RBM500 battery monitor doesn't require much power, saving battery life:Īlso, the unit allows the user to set the Shutdown Voltage (PowOff setting) for the battery monitor. ![]() The physical dimensions of the battery monitor (LCD display) are 3.9 x 2.4 x 0.7 inches (99 x 61 x 18 mm), and it weighs only 2.6 oz (~75 g), making it easy to install in the most suitable place - very important for crowded RVs, boats, and similar. Note: IMHO, Renogy RBM500 and similar battery monitors should be used to monitor dual-purpose and deep-cycle batteries while being used as deep-discharge batteries. The maximum monitored current is 500 Amps, both charging and discharging currents.Īs such, the Renogy RBM500 battery monitor can monitor even starting/cranking batteries used to start smaller diesel and especially gas engines. The supported capacity of the monitored batteries is between 0.0 Ah, which means that the unit is good for practically all automotive, marine, and light-industrial batteries. However, for the monitor to work properly, it must be connected properly - more on that later. ![]() Supported operating voltages are between 10V and 120V - that means that the Renogy RBM500 battery monitor can monitor two or more 6V batteries connected in series, one or more 12V batteries connected in series, etc. Renogy RBM500 battery monitor supports the use of various Lead-Acid (AGM, Gel-Cell) batteries, Lithium Iron Phosphate (LiFePO 4) batteries, Lithium-ion batteries, and even Nickel-Metal-Hydride (NiMH). Renogy RBM500 Battery Monitor Features and Specifications Renogy RBM500 battery monitor supports the use of the most common batteries in use today and allows the user to reprogram it via a simple and easy-to-use interface. Renogy RBM500 10-120V 500A Battery Monitor is a reliable, low-power, and rather easy-to-install battery monitor suitable for cars, RVs, boats, yachts, off-the-grid applications, and similar.
