The Pro BMS series voltage and ammeter is a new coulomb meter that can measure various physical parameters such as voltage, current, power, charge and discharge capacity, watt-hour, time, etc. At the same time, parameters can also be set to realize various protection functions such as overvoltage protection, undervoltage protection, overcurrent protection, overpower protection, overtemperature protection and time-limited protection. The meter can automatically identify the direction of current flow In addition, the battery capacity can be monitored in real time and the measured data is displayed on a color LCD, which displays comprehensive and user-friendly information. The Pro BMS series voltage and ammeter adds the function of displaying and exporting voltage and current curves based on the original functions. At the same time, it can be controlled by mobile APP and communication.
