Digital Battery Indicator Hour Meter Multifunctional Gauge IP65 Waterproof for Electric Cars Carts Lawn Mowers Item Type: Battery indicator hour meter Material: ABS Timing Range: 0-999999H Timing Accuracy: 0.1H/1H Operating Voltage Range: DC6-80V Applicable Voltage: 12V 24V 36V 48V Display Mode: LED, LCDBattery: 1 x CR2430 3.0V capacity 270mah (built in) Features: 1. Timing function A. Record the cumulative working time of the equipment. B. Timing range: 0-999999H, cannot be reset when totaling C. It can record the time of a certain work of the equipment. The single timing range is: 0-999999H, and the single timing can be reset. D. Timing accuracy: 0-99999.9H is 0.1H, 100000-999999H is 1H 2. Power function A. Power display: 10 LED lights in 3 colors to display the power in a single grid B. Power on detection function: automatically display the current remaining power when power on. C. Voltage identification function: automatically identify 12V/24V/36V/48V voltage when powered on. D. Low battery reminder: When the remaining power is 20%, the second yellow light flashes, and when the remaining power is 10%, the first red light and the second yellow light flash alternately to remind charging. E. Discharge delay function: When the battery capacity is greatly consumed (such as the electric vehicle is climbing a hill), there is a delay of 155S to prevent the power meter from rising and falling too fast, so that the user can know the actual battery capacity. F. Charging delay function: when the battery is charging, it will be displayed in the form of a running water light, and the charging will increase by one gear every 200S. 3. Battery type selection A. 19 kinds of battery curves B. A set of custom parameters, users can set the charging and discharging parameters by themselves according to the battery parameters Vent value setting range: 1.40-2.20V, default 1.73V Full power value setting range: 1.70-2.30V, default 2.04V Charging value setting range: 1.80-2.50V, default 2.10V The number of a single core of the battery, the setting range is 5-26. The default is 6 4. Voltage function A. Power on and display the current battery voltage in real time. 5. Output function A. When the power is greater than or equal to 10%, the relay is closed. B. When the point power is less than 10%, the relay is disconnected.Advantages: 1. Reverse connection protection can prevent the electric meter from being burned out due to the positive and negative connection. 2. Equipped with an 8pin plug, which is convenient for installation.  3. Embedded installation, bracket fixed. Fitment: Widely used in motorhomes, electric vehicles, carts, and other vehicle industries; electric lawn mowers, chainsaws, chippers and other garden machinery; construction vehicles, tractors, excavators, rammers and other construction machinery; forklifts, Warehousing and handling equipment such as stackers and material handling vehicles; cleaning equipment such as floor scrubbers and cleaning vehicles; and other battery equipment.
