CELL HOLDER 21700 (3X4)

CELL HOLDER 21700 (3X4)

The CELL HOLDER 21700 (3X4) is a 21700-format lithium battery cell holder / spacer designed to organize cylindrical cells in a 3X4 grid layout. It helps maintain cell alignment, separation and a repeatable module shape before nickel-strip welding, BMS wiring, insulation and final enclosure assembly.

Battery packs built from cylindrical cells benefit from a defined mechanical pattern because every cell must remain correctly positioned while the electrical interconnects are added. This holder establishes the named 3X4 geometry for 21700 cells, reduces unnecessary cell movement and maintains a deliberate gap between neighboring metal cans. The result is a cleaner, more professional battery-module layout for prototype and repeat production. Current ARB listings and independent Indian battery-component sellers use the same commercial terms for this product class: 21700 cell holder, battery spacer, cell spacer and battery pack support bracket.

Durable insulating engineering plastic is widely used for this holder class because it provides lightweight mechanical support without forming a conductive path between adjacent cells. The holder keeps cell centers consistently arranged so nickel strip or other interconnects can be positioned more evenly during assembly. The spacing also leaves room for air movement around the cell group and helps reduce shell-to-shell rubbing in packs exposed to handling or vibration. The grid format gives production operators a clear row-by-column reference for cell placement and module kitting. In practical pack-building terms, it works as a 21700 cell holder 3x4, 21700 battery holder 3x4, lithium battery cell spacer, EV battery cell holder and battery pack spacer for organised cylindrical-cell module construction.

The CELL HOLDER 21700 (3X4) is intended for cells in the 21700 physical form factor. Selection is therefore based first on cell size and module geometry; the holder can support compatible lithium chemistries that use the same cylindrical format. Use the 3X4 version where the battery enclosure and interconnect plan are built around that layout, and use HEXA or L-type versions where the module design follows the corresponding specialized footprint. Pair the holder with suitable cell-end insulation, interconnect material, BMS, wiring and enclosure protection for the finished battery system.

Applications

• high-energy e-bike, e-scooter and EV battery packs.

• portable power stations and performance-oriented lithium modules.

• solar, UPS and compact ESS battery packs.

• Battery production lines assembling 3X4 cell groups with repeatable spacing and polarity orientation.

• Prototype, repair and custom battery-pack projects requiring organised 21700 cell positioning before interconnection and enclosure assembly.

Installation Guide

Arrange the 21700 cells in the required polarity pattern and seat them evenly into the 3X4 holder without forcing the plastic. Where the pack uses holder pieces at both ends, keep the top and bottom patterns aligned so the cells remain parallel. Complete insulation and interconnection work only after the cell group is mechanically stable. Keep conductive tools controlled around exposed terminals and inspect the holder for cracks, pinched insulation or tilted cells before the battery module is closed inside its enclosure.
