How do your 21700 battery holders handle the increased mass of the cell?

We engineered the enclosure geometry and contact pressure to specifically address the heavier mass of 21700 cells. Using heavy-gauge Phosphor Bronze or Spring Steel contacts, our holders ensure rigid cell retention and prevent contact bounce under heavy mechanical shock and vibration.

Are your 21700 enclosures suitable for high-drain applications?

Yes. The terminal contacts are precision-stamped and finished with industrial-grade Tin or Gold plating to maintain low contact resistance (≤30mΩ), ensuring stable and low-loss power transmission for high-drain (10A-20A+) industrial and EV applications.

Can I get 2D footprint specs to verify 1:1 replacement?

Yes. To ensure 1:1 precision replacement for standard Keystone or MPD equivalents, deployment of our Senior NPI Engineering Team is required. Request Engineering Support to review the Technical Datasheets and 2D Footprint Specs matching your layout within a strict 12-hour SLA.

21700 Battery Holders | High-Drain THM & SMT Enclosures

Engineering Overview We engineered our 21700 battery holders to support high-density power architectures, specifically targeting EV battery management systems, power tools, and industrial instrumentation. To accommodate the increased mass and thermal output of 21700 cylindrical cells, these enclosures are molded from rigid, UL 94V-0 rated High-Temp plastics (LCP or PA46) to maintain dimensional stability across aggressive wave and reflow soldering profiles.

Contact Mechanics & Current Handling Our test data confirms absolute cell retention and sustained low contact resistance (≤30mΩ) under severe mechanical shock profiles. We precision-stamp the terminal contacts from heavy-gauge Phosphor Bronze or Spring Steel, deploying industrial-grade Tin or Gold plating to eliminate oxidation risks. This architecture ensures reliable, low-loss power transmission for high-drain (10A-20A+) applications over thousands of insertion cycles.

Engineering Protocol To ensure 1:1 precision replacement for standard Keystone or MPD equivalents, deployment of our Senior NPI Engineering Team is required. Please review the [Technical Datasheets] and [2D Footprint Specs] to verify exact pad and lead layout parameters.
