On This Page Overview
Product Overview
The Baitongkexin BT-BD02 is a cell-level charge-discharge and grading unit for battery teaching and preparation work. Eight independent channels use four-wire current and voltage acquisition to record individual cell behavior. Instructors can use the results to teach capacity comparison, test consistency and cell selection. The unit tests cells within its specified channel limits; it is not a high-voltage pack tester or a guarantee that a selected group is suitable for assembly.
Core Functions
Independent Cell Channels
Each channel supports its own cell test, allowing learners to compare results from a defined batch under a consistent procedure. The fixture and test profile must suit the cell chemistry and terminals.
Several Test Modes
Charge modes include constant current, constant voltage, combined constant current/constant voltage and constant power. Discharge modes include constant current, constant power and constant resistance.
Recorded Results for Comparison
The PC software provides charge-discharge records. Learners can compare voltage, current and capacity results and explain why test conditions matter when grouping cells.
Practical Training Tasks
Test planning
Learner Practice
Choose an approved cell profile within channel limits
Evidence for Review
A documented profile and cell identification record
Capacity comparison
Learner Practice
Run a supervised test on a selected batch
Evidence for Review
A comparison of channel results under stated conditions
Grading decisions
Learner Practice
Review measured results against instructor criteria
Evidence for Review
A justified grouping decision, not an automatic pack-safety approval
Equipment and Scope
The configuration includes an eight-channel unit, copper crocodile-clip fixtures and PC test software. Confirm the host computer, fixture suitability, calibration documents and any export or reporting options.

Configuration and Ordering
Reference Laboratory Quantity
1 unit
This quantity belongs to the reference laboratory equipment schedule. Confirm the quantity for your project in the quotation.
Configuration and Procurement
Provide the cell chemistry, format, terminal arrangement and intended test profile. Confirm how voltage, current and power limits interact, plus the applicable accuracy specification and calibration conditions. Compatibility should be documented for the exact cell type rather than inferred from a form factor such as 18650.
Details for Your Inquiry
Provide cell chemistry, format, terminals and intended test profiles to specify fixtures, software and the host-computer package.
Product Questions
Can it test an assembled EV battery pack?
No. The listed channels are for low-voltage cell testing within their individual limits. A pack requires appropriately rated test equipment.
Is a computer supplied?
PC software is listed, but the host computer is not clearly identified as part of the supply. Request an itemized package.
