Battery Monitor with Shunt 400A 0-120V 2.4inch Display Wireless Voltage Current Meter for Car Motor Boat RV Motorhome Golf cart Solar System

【Easy To Read】The display module adopts a 2.4inch HD color LCD screen, the display is clearer; the buttons are made of silica gel, which increases the comfort of a good feel on the basis of good operation fluency and fast response speed.

【Universal Battery Monitor】The product automatically recognizes and detects the current in both charging and discharging directions. When charging, the color of the current in the display module is green; when discharging, the color of the current in the display module is blue. Suitable for a variety of batteries: ternary lithium batteries, lead-acid batteries, lithium phosphate batteries, etc., as long as the battery is within the voltage measurement range.

【Accurate Measurement】The shunt and screws are made of pure copper material, which has good conductivity, low heat generation and low power consumption. In the standby state, it will not consume too much battery power.

【Support mobile APP control】 After the APP is downloaded and installed, you can view all relevant data and curves on the APP through the Bluetooth connection, and set all functions through the APP.The mobile phone APP has the function of viewing the curve, which can display the real-time curve and historical curve of voltage and current, and supports the export of historical data.

【Multifunction】The product can be set with over-voltage, under-voltage, over-current, over-power, and external over-temperature protection. When the value exceeds the protection value range, the output state of the instrument is closed (need to be used with a relay) to prevent damage to the electrical equipment. The protection recovery time and delay time can be set, suitable for various occasions.The product has added a self-calibration function, and the current and capacity values can still remain accurate after a long time of work.
