Cell boards for pouch or small cylindrical cells

Open PCB assembly

Each of these cell boards handles a single pouch or small cylindrical cell.
  • Measures and reports voltage and temperature
  • Mounted onto the cell
  • Inobstrusive: fits within the gap between small cylindrical cells or between tabs for large pouch cells
  • A single communication wire is used between adjacent cells in a bank

Pouch and small cylindrical cell boards


These cell boards can be used with all pouch and small cylindrical cells.

Single boards offer flexibility, as they can be used in a variety of cell arrangements.

These cell boards can be used with a variety of prismatic cells. They are available in various lengths, to accommodate various terminal spacings.
