Expandable cell adapter for round battery cells

Expandable cell adapter for round battery cells

Feinmetall features a modular design, where one base adapter can be combined with various interchangeable special contact pin holders. This allows for testing up to 60A.

For contacting round cells of the 18650, 21700, and 26650 types, we offer an expandable cell adapter with a modular design for individual laboratory tests.

Advantages:

  • The adapter can be customized for cell diameter and cell length
  • Variable adjustment of cell diameter
  • Exchangeable contact elements
  • Variable adjustment of cell length
  • Cell contact is facilitated through a manual lever.
  • Different individual adapters can be combined into a multiple adapter using a tongue and groove mechanism. This enables simultaneous testing of multiple cells.
  • Effective solution for connecting round cells

Heynen can also provide high-current solutions for batch testing in a production environment.
