Cell board, small cylindrical, single cell

1SC0100, standard Cell Boards for a single 18650 and 26650 cell - Notice: This product has been discontinued and is no longer available

Each of these cell boards handles a single small cylindrical cell
(as opposed to a 1SCxxxx, which handles multiple cells per board).
  • Matched to industry standard 18650 and 26650 sizes
  • Mounted on the side of the cells, by their welding tabs
  • One Cell Board per cell (or set of multiple cells in parallel)
    • Highest flexibility, as they may be used with any cell arrangement (though at the cost of slightly more assembly effort, compared to multi-cell cell boards)
  • Very thin, components are placed in space between cells: as little as 0.05" is added to battery dimensions
  • A single communication wire is used between adjacent cells in a bank
  • These cell boards require a BMS master to form a complete BMS
26650 size cell single cell Small cylindrical cell board, single


These cell boards can be used with blocks of 18650 or 26650 small cylindrical cells.

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

Installation is straightforward, though be forewarned that it requires more skill than other Lithiumate cell boards:

  1. Place cell board on the cell
  2. Fold the tabs from the cell down onto the cell board
  3. Solder the tabs
  4. Connect adjacent cell boards with a communications wire

For more information, see the installation instructions.

Item Notes Dimensions
PCB width 0.75" / 19 mm
PCB Length 2.5" / 63.5 mm
PCB thickness (additional thickness of battery, with electronics nested in space between cells) 0.031" / 0.8 mm
Thickness W/components, mid-bank board 0.071" / 1.79 mm
Connector height End board, right angle 0.27" / 6.8 mm



Each bank requires a positive cell board on its most positive cell, a negative cell board on its most negative cell, and mid-bank cell boards in the remaining cells.
(The automatic quote form will select the correct number of each type of board for you.)


Right angle connectors are standard on full bank and end boards. Versions with straight connectors or without connectors are available with quick turnaround.

Part numbering

Part number: 1SC0100M:

  • 1 = Cell Board
