Cell modules for prismatic cells

Mechanically rugged, electrically protected

Each of these cell modules handles a single prismatic cell.
  • Measures and reports voltage and temperature
  • Matched to most sizes of prismatic cells
  • Mounted on the top of the cell, through ring terminals
    • Reliable mechanical mounting and direct electrical connection
  • Inobstrusive: fits within the terminal bolts
  • A single communication wire is used between adjacent cells in a bank
  • For use as part of a Vinci or Lithiumate BMS
Primatic cell module
Primatic cell module


These cell modules can be used with most prismatic cells.

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

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

ss = terminal spacing [cm]
w = balance power code: 6: 1 W; 7: 2 W; 8: 5 W; 9: 10 W

Example: Part number 1PR4117M

  • 3 = Vinci
  • PR = Prismatic cell module
  • 4 = M8 bolt (bolt size = 2 x code)
  • 11 = 110 mm: maximum center-to-center spacing of cell terminals, in cm
  • 7 = 2 W balance power (available: 6: 1 W; 7: 2 W; 8: 5 W; 9: 10 W)
  • M = mid bank (available: M = mid-bank; P = positive end, cable; N = negative end, cable; H = positive end, fiber optic; L = negative end, fiber optic)


General specifications

  • 1.8 to 4.5 V, 1.25 mV resolution (Vinci)
  • Protected against miswiring, up to +/- 50 V
  • -40 ~ 85 °C, 0.5 °C resolution (Vinci)
  • Sealed
  • Dual redundant
    • Voltage measurement (against voltage reference failure)
    • Temperature measurement (against thermistor failure)
    • Protection (analog fault detector in case of digital BMS failure)
  • Balance current from 100 mA to 3 A, depending on terminal spacing

Detailed specifications are in the Vinci BMS Manual.


Installation is straightforward:

  1. Mount cell module's ring terminal on the cell's negative terminal
  2. Mount other ring terminal on the cell's positive terminal
  3. Connect adjacent cell modules with a communications wire
