VATRER POWER Meter Monitor with 500A Shunt and LCD Low Power Alarm 8-120V Voltage/Current

"1% High-Precision Measurement": The shunt-type design achieves ultra-high-precision measurement within ±1%. In addition to voltage, current, power, and capacity, it also displays remaining charge, charge/discharge time, and remaining capacity percentage in real time. "8-120V wide voltage compatible" Compatible with various types of batteries including lithium, lithium iron phosphate (LiFePO4), lead (GEL/AGM), nickel-metal hydride, etc. *Shunt use is required. "Low Capacity Alarm Function": Displays a warning and sounds a buzzer every 10 seconds when the remaining capacity is below 10%. Prevents over-discharge and extends battery life. "Easy Installation Design": Includes a shunt holder for both freestanding and wall-mounted installation. A noise-shielding cable (6m) allows for monitoring from a distance. "High-visibility LCD screen": Backlit LCD provides clear display even in dark places. One-button operation displays a list of key parameters. "Data retention function": Automatically saves measured values even in the event of a sudden power outage. Adjustable backlight brightness ensures no sleep disturbance during nighttime use. This product is a high-precision power meter (coulometer) that uses a current detection method, and can accurately detect the voltage, current, power, actual capacity, and remaining time of the power pack. It is designed to allow for constant and accurate monitoring of the operating status. This product has a wide range of applications, including touring cars, wheelchair lifts, electric vehicles, emergency power supplies, energy storage devices, measuring instruments, medical equipment, and various other measuring devices.
