CELL HOLDER 21700 (4X7)

The Cell Holder 21700 (4X7) is a premium-quality battery spacer designed for the safe and efficient assembly of lithium battery packs using 21700 cylindrical cells. With a 4x7 configuration, this holder securely accommodates 28 cells, ensuring proper alignment, consistent spacing, and enhanced structural stability throughout the battery pack.

Proper cell spacing is essential for battery safety, cooling efficiency, and long-term performance. The 21700 Cell Holder (4X7) helps maintain uniform gaps between cells, allowing improved airflow and heat dissipation. This reduces heat buildup during charging and discharging cycles, helping improve battery efficiency, reliability, and lifespan.

Manufactured from durable and heat-resistant engineering plastic, this holder is built for long-lasting performance in demanding applications. The interlocking snap-fit design allows quick and easy battery pack assembly while securely holding each cell in place. Its strong construction minimizes vibration and movement, creating a safer and more durable battery pack structure.

The 21700 Battery Cell Holder is widely used in electric vehicles, e-bikes, e-scooters, solar energy storage systems, inverter batteries, UPS backup systems, portable power stations, and DIY lithium battery projects. It provides a professional solution for building organized and high-performance battery packs.
