QOMOLANDER intelligent battery management system can real-time monitor battery status, collect, store and process the information during battery operation. With a Bluetooth connection, it can exchange information with external devices to display battery information and diagnose battery issues. This technology can also extend the lifetime and enhance the stability of the battery. 1. Real-time display of voltage, current ,SOC ,SOH, temperature, other parameters of battery. 2. Real-time display the voltage of battery cells. 3. Real-time display the maximum and minimum voltage of the cell, the voltage difference and the cell balance. 4. Real-time display of over-voltage, under-voltage, over-current, over -temperature, low-temperature, short circuit and other alarm status. 5. Modifying battery parameters. 6. Upgrading battery program. 7. Charging and discharging switch on or off. I hope QOMOLANDER can help you to better understand the convenience of lithium batteries operation.

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.
