Mon,tooth Er,400a 0120v Voltmeter Ammeter Te Tool,wirele

Our smart battery monitor supports bluetooth connection for mobile APP control, all settings and parameters are read out on a mobile device. Can measure voltage, current, , charge and discharge capacity, watt hour, time, etc. Also enables parameters setting, auto recognition on the current direction, and monitor the battery capacity in real time.The battery detector is suitable for ternary lithium battery, lithium phosphate battery, etc.You can set over voltage, under voltage, over current, overpower, and external over temperature protection. When the value exceeds the protection range, the output state of the instrument is closed (it needs to be used with a relay) to prevent damage to the electrical equipment. Protection recovery time and delay time can be set.Our wireless voltage current meter automatically recognizes and detects the current in the direction of charging and discharging. When charging, the current color is green; when discharging, the current color is blue; the ampere hour, watt hour, and time data can be cleared during the measurement process without affecting the measurement. Voltage and current values can also be fine tuned to capacity.This multimeter can be used as battery voltage meter, battery capacity tester and temperature indicator panel for car, marine, RV, boat, electric bike etc.Type:-140F Coulomb Counter(400A)color:BlackMaterial:plasticPackage Contents:1 set x Battery MonitorOnly the above package content, other products are not included.Note: Light reflection and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
