MS-3985 220V Charging 40A Discharging 100A, Battery Charging/Discharging Tester Load Group

This battery charge/discharge tester load bank integrates constant current discharge, intelligent charging, 

single-cell monitoring, and activation functions. It offers multiple uses, reducing enterprise costs and 

the workload of maintenance personnel, providing a comprehensive and scientific testing method for

 battery and UPS power supply maintenance. It is used in telecommunications, base stations, power, and other sectors. It performs deep discharge and then recharge as needed, keeping the battery pack in optimal condition and extending battery life, making it the best assistant for battery maintenance.

1. DC220V voltage charge/discharge function: A single unit can meet the charge/discharge testing needs of battery

 packs at DC220V voltage level.

2. Constant current discharge function: The constant current discharge current is continuously adjustable, 

accurately measuring the battery pack capacity.

3. Intelligent charging function: Intelligent three-stage charging with continuously adjustable charging current meets 

the charging and maintenance needs of battery packs.

4. Activation function: The number of charge/discharge cycles can be set to activate the battery pack, effectively improving

 the capacity of individual cells.

5. Features online monitoring and capacity analysis: Real-time online monitoring and display of all test data: 

current, battery pack voltage, individual cell voltage, discharge time, and capacity; at the end of the verification

 discharge test, it can quickly analyze the remaining capacity of each cell.

6. Features individual cell voltage detection: Employs a wireless monitoring module compatible with 

1-16V individual cell voltage monitoring; each module can monitor 12 cells simultaneously.

7. Features real-time individual cell voltage detection: Automatically displays the current voltage of each individual cell 

on the main unit screen, and automatically displays the six cells with the lowest voltage in real time.

8. Features multiple alarm prompts: Automatic alarm and discharge stop for test current exceeding or falling below

 set values, voltage exceeding or falling below set values, reverse polarity, overheating, short circuit/overcurrent, fan malfunction, etc.

9. Features pause and parameter modification during discharge: Discharge can be manually paused and discharge

 settings (lower limit voltage, discharge current, discharge time, etc.) modified during the discharge process without 

terminating the test. Unlike traditional discharge testers that require terminating the discharge process (D) and then 

restarting the discharge test, this device offers remote discharge control:

10. It features remote discharge control functionality: The PC-based host computer software connects to the charge/discharge

 tester via an RS485 communication cable, enabling PC-controlled discharge.
