5 Channel Cylindrical Cell Sorting Machine
Model: MD-BS05
Usage: cylindrical cell voltage and internal resistance sorting
Sorting channels: 5 sorting channels
Cell type: cylindrical lithium cells; fixture confirmed by cell size
Control: PLC and PC control
Warranty: 1 year
5 Channel Cylindrical Cell Sorting Machine is used for cylindrical lithium battery cell internal resistance (IR) and voltage testing before battery pack assembly. After testing, the machine sorts cells into different channels according to the preset voltage and IR ranges, helping battery pack manufacturers group cells with similar electrical performance.
This 5-channel model is a compact option for cylindrical cell voltage and internal resistance sorting when the production volume is moderate or when a factory needs a practical machine for cell grouping before small and medium battery pack assembly.
Why Cylindrical Cells Need Sorting
Even cells from the same supplier or the same batch can have different voltage and internal resistance values. If cells with large parameter differences are assembled into one battery pack, the pack balance, discharge consistency and service performance may be affected. Cell sorting helps prepare more consistent cell groups before spot welding, BMS assembly and pack aging.
Machine Function
The sorting machine is composed of a mechanical structure, feeding system, testing system and control system. Cells are placed into the feeding bin, then the roller mechanism moves each cell to the test position. The test probes contact the positive and negative terminals, the tester reads voltage and internal resistance, and the controller sorts the cell into the corresponding channel according to the preset range.
Key Features
- 5 sorting channels for cylindrical lithium battery cell grouping
- Tests voltage and internal resistance before battery pack assembly
- Suitable for cylindrical lithium cells; fixture and feeding parts should be confirmed according to the actual cell model
- PLC and PC control for feeding, handling, testing and sorting control
- Voltage and internal resistance testing system for cell grouping
- Compact and reasonable equipment structure with simple operation
- High-quality thick cold-rolled sheet metal and aluminum frame structure
- Universal movable casters make the machine easier to move in the workshop
5-Channel Compact Sorting
The 5-channel structure is suitable for customers who need reliable automatic cylindrical cell grouping without a large sorting footprint. It supports the same core sorting principle: measure each cell, compare the result with the set ranges, and place the cell into the corresponding channel.

FAQ
What does the battery sorting machine test?
It tests cylindrical cell voltage and internal resistance, then sorts cells into different channels according to the set ranges.
Can the machine support both 18650 and 21700 cells?
The fixture should be confirmed according to the actual cylindrical cell size. Please send the cell model and dimensions before quotation.
Why choose a computer software version?
The computer software version is useful when the customer needs data collection, sorting records and convenient parameter management.
Why choose a touch screen version?
The touch screen version is useful when the customer wants direct machine operation and simple on-site parameter setting without focusing on computer-side data management.
