3, Functions

3.1 Discharge test

3.1.1 can continuously set the discharge current. Make constant-current discharge according to the set discharge current, monitor the voltage of battery pack and signal battery, testing the capacity of signal battery and battery pack (capacity test).

3.1.2 set of various discharge stop conditions

A. The voltage of battery pack B The voltage of signal battery

C. Discharge time D Discharge capacity

3.1.3 Applicable to a variety of single cells: 2V, 4V, 6V, 12V (other voltage can be customized)

3.2 Quick test function

Short time discharge (around 10-20 minutes), quickly test the internal resistance and discharge capacity of signal battery, quickly identify the performance of battery.

3.3 When power failure or actual load discharge, on-line automatically monitoring the voltage of signal battery, the voltage of battery pack and discharge current, record the discharge capacity of the battery, ensure the judgment of battery status.

3.4 Monitoring the charging voltage after discharge. After discharging, when the battery pack is charging by the charger, this device can monitor the voltage of signal battery and pack battery during the process of charging, it can monitor the charging current (equipped with current clamp) and set the alarm.

3.5 Wireless monitoring function to PC. Realize the PC to discharge monitoring system for wireless data monitoring within 100M, alarm function.

3.6 Data management.

Perfect computer management and analysis monitoring software, with strong function of data analysis and processing, use advanced mathematical models to make comprehensive computational analysis for a number of measurements of the battery, accurately judging the battery performance, and check real-time operating status and historical data of the battery, report each parameter, curves and generate reports.
