Main functions:                                                                                           1. Online monitoring function: 
When the battery pack is under the state of online, it performs real-time monitoring for battery pack and cell voltage, charge/discharge current, charge capacity, discharge capacity.                                                           2. Discharge test function:
It performs constant current discharge by the load after the battery pack is removed from system. It can display discharge current、battery discharged capacity、battery pack and cell voltage, discharge time and etc at real time. Main features:Expandability:
 The user can set up cell quantity and increase discharge current by external load.
Safety and reliability:
It sets up four conditions to stop discharging when performing check discharge test:
1） whole pack voltage; 2）cell voltage; 3）discharge time; 4）discharge capacity.
It can also manually stop the test process.
Convenience and speediness 
Connect to PC, It can carry out test control directly and real-time monitoring for instrument, meanwhile performs pattern analysis by software on PC.
English menu, simple operation, and clear flow, brief clue of every interface and mistaking operation protect.
High measurement accuracy and great stability: 
 No need of manually correcting voltage during operation.                     AC/DC power supply, seamless switching
Built-in cell voltage collector
Small volume and light weight
Complete analysis software
It is English designed, and it could automatically create histograms and curves of voltage, current, inner resistance etc, it could also create test report (Excel and Word format) and put forward maintenance suggestions.
