Feature: 1. Battery Meter: Can measure various physical parameters such as voltage, current, power, 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. 2. Accurate Work: When charging, the current colour is green, when discharging, the current colour 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 ensure accurate capacity. 3. Reliable Uses: 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, and it needs to be used with a relay to prevent damage to the electrical equipment. Protection recovery time and delay time can be set. 4. Smart Control: Supports Bluetooth connection for mobile APP control. After downloading and installing the APP, all functions can be set through the built in Bluetooth connection through the mobile APP. With self calibration function, the long term working current and capacity values can still be accurate. 5. Broad Utility: The shunt and screw are made of brass material, which has good conductivity, low heat generation and low power consumption. In standby mode, it will not consume too much battery power. Applicable to ternary lithium battery, lithium phosphate battery, etc., as long as the battery is within the voltage measurement range.
