Cell board, prismatic, multiple cells

1PMxxxx, Cell Boards for multiple prismatic cells - Notice: This product has been discontinued and is no longer available

Each of these cell boards handles a number of prismatic cells
(as opposed to a 1PR0xxx, which handles a single cell per board).
  • Custom made to fit most sizes of large prismatic cells
  • Placed horizontally on top of cells, between the terminals
  • Connected to cells through ring terminals
  • One Cell Board per cell (or set of multiple cells in parallel)
  • Flat shape: doesn't extend past current carrying bolts
  • These cell boards require a BMS master to form a complete BMS
Prismatic cell multiple prismatic cells with cell board Multiple prismatic cell board


These cell boards can be used with a variety of prismatic cells, in a variety of configurations.

Installation is straightforward:

  1. Mount cell board on area between cell terminals
  2. Mount cell board's ring terminals on the cells' terminals

A bank can be handled in one of two ways:

  • Full bank: a single cell board handles the entire bank
  • Split bank: 2 or more cell boards handle the bank:
    • A positive cell board on its most positive cell
    • A negative cell board on its most negative cell
    • Zero or more mid-bank cell boards on any remaining cells
Bank Type Range Cable to
BMS board
Wires to adjacent cell boards
Full Full-bank Handles the entire bank
Range of Full-Bank cell board
Through two 2-pin connectors N.A.
Split Positive End Handles the post positive portion of the bank
Range of Positive-End cell board
Red and black wires through a 2-pin connector A single wire to the next cell board
Mid-bank Handles a central portion of the bank
Range of Mid-Bank cell board
N.A. Two single wires, one to the previous cell board, one to the next one
Negative End Handles the post negative portion of the bank
Range of Negative-End cell board
White and green wires through a 2-pin connector A single wire to the previous cell board


  • When a single cell board handles the entire bank, a "Full bank" cell board is used
  • When 2 cell boards handle a bank, a "Positive end" cell board is used at the most positive end of the bank, and a "Negative end" one is used at the most negative end of the bank
  • When 3 cell boards handle a bank, a "Positive end" cell board is used at the positive end, a "Mid bank" one is used in the middle, and a "Negative end" one is used at the negative end
  • When n cell boards handle a bank, a "Positive end" cell board is used at the positive end, n-2 "Mid bank" ones are used in the middle, and a "Negative end" one is used at the negative end


Right angle connectors are standard on full bank and end boards. Cell boards with straight connectors or no connectors are also available

Part numbering

Part number: 1PM1234B:

  • 1 = Cell Board
  • PM = prismatic multiple
  • 12 = Number of cells in series (available: 2 to 16)
  • 34 = Centerline spacing between cells
  • B = full bank (available: B = full bank; M = mid-bank; P = positive end; N = negative end)


To order, please see the Lithiumate BMS ordering form.

There is an additional NRE charge for these cell boards, for PCB layout and manufacture set-up.

As these cell boards are made to order, to order please contact us first.
