1. Product Overview

This 1×4 32700 battery holder is designed to position four compatible cylindrical cells in one straight row during battery-pack assembly.

The holder supports consistent cell alignment and spacing, making it easier to construct organised battery modules. Its moulded frame helps reduce direct contact and movement between adjacent cells while providing a more stable base for connecting cells with nickel strips or busbars.

The holder is a mechanical battery-pack component only. It does not provide electrical connections, cell protection, balancing or battery-management functions.

2. Technical Specifications

The exact internal diameter, external dimensions, plastic grade, heat resistance and flame-retardant rating should be confirmed before use in a production battery pack.

3. Main Features

• Holds four cylindrical cells in a straight 1×4 arrangement
• Helps maintain uniform spacing between cells
• Supports organised and repeatable battery-pack assembly
• Reduces unwanted cell movement
• Helps prevent direct rubbing between adjacent cell bodies
• Provides access to cell terminals for welding or busbar installation
• Interlocking side features may support larger modular layouts
• Lightweight moulded construction
• Suitable for both small projects and larger battery modules
• Can be used at the positive and negative ends of a cell group when required

4. Electrical Configuration

The 1×4 layout describes only the physical arrangement of the cells. It does not determine the electrical configuration.

Depending on the nickel-strip or busbar connections, four cells may be configured as:

• 1S4P: Four cells connected in parallel
• 4S1P: Four cells connected in series
• Part of a larger series-parallel battery module

The electrical configuration must be designed according to the required battery voltage, capacity, current and BMS specification.

5. Suitable Applications

This holder may be used for compatible 32700-cell battery packs in:

• Solar-energy storage batteries
• Inverter and UPS battery packs
• Electric scooters
• E-rickshaws
• Portable power systems
• Robotics and automation projects
• Backup-power systems
• DIY lithium battery packs
• Battery repair and rebuilding work
• Custom cylindrical-cell modules
• Educational battery-pack projects

Suitability depends on the dimensions of the selected cells and the mechanical, thermal and electrical design of the complete battery pack.

6. Cell Compatibility

Before ordering or assembling the pack, confirm:

• The cells are cylindrical 32700-size cells.
• The actual cell diameter fits the holder securely.
• Any cell sleeve, insulation ring or protective covering does not make the cell too wide.
• The holder does not excessively compress or damage the cell sleeve.
• Sufficient space remains for nickel strips, busbars and insulation.
• The holder fits inside the intended battery enclosure.
• The selected cell chemistry and voltage are compatible with the charger and BMS.

The term “32700” generally refers to a cell approximately 32mm in diameter and 70mm long. Actual dimensions can vary by manufacturer.

7. Installation Guidance

• Inspect every cell for damage before assembly.
• Check the voltage and internal resistance of all cells.
• Use cells of the same model, capacity, condition and production batch whenever possible.
• Insert each cell carefully without damaging its insulation sleeve.
• Keep all cells aligned in the required polarity direction.
• Use one holder at each end of the cell group when the pack design requires support at both ends.
• Confirm cell polarity before welding nickel strips or attaching busbars.
• Use suitable terminal insulation rings and insulating sheets.
• Keep conductive material away from unintended cell terminals.
• Secure the completed module against vibration and movement.
• Use appropriate cushioning and insulation when installing it inside an enclosure.
• Verify all electrical connections before connecting the BMS.

8. Important Usage Note

This holder provides mechanical positioning only. It does not replace:

• Fish paper or electrical insulation
• Cell-terminal insulation rings
• Nickel strips or busbars
• A compatible BMS
• An appropriately rated fuse
• Thermal protection
• Vibration-resistant cushioning
• A suitable battery enclosure
• Correctly rated cables and connectors

The holder’s plastic material and interlocking joints should not be treated as the pack’s only structural or electrical protection.

9. Safety Information

• Do not force oversized cells into the holder.
• Do not use cells with torn sleeves, dents, swelling, corrosion or leakage.
• Prevent metal tools from shorting the cell terminals.
• Verify cell polarity before welding or connecting busbars.
• Keep sufficient insulation between the cell terminals and enclosure.
• Do not expose the holder to temperatures above its verified material rating.
• Do not rely on the holder alone to secure a battery in a high-vibration application.
• Use a BMS and charger suitable for the battery chemistry and series configuration.
• Battery-pack assembly should be performed by someone familiar with lithium-battery safety.
