High current measurement resolution: 10 mA (0,01A) Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health Shunt selection capability up to 10.000 Amps 500 Amp quick connect shunt and connection kit
12 volt battery monitor for rv generator#
Programmable relay, to turn off non critical loads or to run a generator when needed Remaining time at the current rate of discharge Battery voltage, current, power, ampere-hours consumed and state of charge Please consult the BMV manual for more information.
Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery. Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or cell. In practice, however, deviations will be seen, that depend on many factors such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacities and much more. Ideally, the midpoint voltage would be exactly half of the total voltage. The midpoint voltage is the voltage halfway along the string. This feature, which is often used in industry to monitor large and expensive battery banks, is now for the first time made available at a low cost, to monitor any battery bank.Ī battery bank consists of a string of series connected cells. Midpoint voltage monitoring (BMV-702 only)
12 volt battery monitor for rv install#
Included: RJ 12 cable (10 m) and battery cable with fuse (2m) no other components needed.Īlso included are a separate front bezel for a square or round display appearance, a securing ring for the rear mounting and screws for the front mounting.Ī quick install menu and a detailed setup menu with scrolling texts assist the user when going through the various settings.Īlternatively, choose the fast and easy solution: download the smartphone app (Bluetooth Smart dongle needed) The shunt connects to the monitor with a standard RJ12 telephone cable. Use the Bluetooth Smart dongle to monitor your batteries on Apple or Android smartphones, tablets, macbooks and other devices.Īll electrical connections are to the quick connect PCB on the current shunt. The BMV-702 features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power consumption in Watts.
Complex software algorithms are needed to take all these variables into account. The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Battery ‘fuel gauge’, time-to-go indicator, and much more
